The character of "Bubbles", played by Andre Royo, was largely based on a real Baltimore drug addict and police informant who went by that name. The real Bubbles, who would slur his speech much more than the fictional character, first started working with the cops near the early 1960's after being arrested for a burglary. He spent the next few decades as an informant, leading to the arrest of several hundred felons and getting paid at least $50 for each one caught. His photographic memory and ability to blend into the scene made him one of the best in the city. Eventually he would start using the hat method portrayed on the series, where he acted as if he was selling hats and would place one of a certain color on the head of those the police should arrest.
Many of the minor characters are played by real-life police officers, politicians and former criminals. In fact, many of the former criminals who act on the show were previously arrested by the real-life cops who act on the show.
According to Michael Kenneth Williams, he secretly struggled with a cocaine addiction during the third season. He never missed a day of work nor was he ever late. He also suffered with an identity crisis due to his popularity as Omar.
According to Sonja Sohn, during the first season she had much trouble remembering her lines causing numerous delays. She says it was due to childhood trauma of growing up in a ghetto and witnessing police brutality. Because of this she was uncomfortable in the neighborhood while filming took place and had issues with portraying a police officer.
When Dominic West first auditioned on videotape from his London home, he tried to have his girlfriend read the lines for the other characters in the scene. But her English accent kept throwing him off and he kept laughing. So West performed the scene himself by leaving pauses where the other character's lines were supposed to be. West admits to imitating Robert De Niro for his audition. At first, the producers found the audition tape "weird" and "comic" but they reconsidered when they concentrated on West's performance. When West was offered the role, he became reluctant because the contract was for five seasons. But his agent convinced him that the show would not last more than one. It ended up lasting five seasons.
Tray Chaney originally auditioned to play the character of Wee-Bey Brice but the producers felt he was too short. They were so impressed with his audition that they created the character of Poot for him to play.
The writers/producers briefly considered doing a sixth season about the influx of Latinos into Baltimore. But none of them knew enough about Baltimore's Latino population to write about it so the idea was dropped.
The character of Avon Barksdale is loosely based on Melvin Williams. Williams was a notorious drug kingpin in Baltimore who was brought to justice by Ed Burns. Williams joined the show as the deacon in season 3.
The character of Sgt. Jay Landsman played by Delaney Williams was based on Jay Landsman, a real-life Sergeant with the Baltimore County Police. He was featured in David Simon's book "Homicide: A Year On The Killing Streets". Landsman himself joined the cast in the third season playing Lt. Mello.
Some of the show's interiors, including McNulty's apartment set and the police station's offices, were constructed inside a former Sam's Club Warehouse store. The zoning for that building dictated that its tenant had to be a retail business, and when the producers got into trouble for renting the building without selling anything from it, they considered opening a store there to sell t-shirts, DVDs, and other show souvenirs before the issue was finally resolved.
In season three, when McNulty is comparing the units skills favorably to those of other Baltimore police he mentions Donald Worden as one of the few police who can match them in skill. Worden is a real life detective who served in the Baltimore homicide unit when David Simon covered it. For at least part of that time he was the partner of Jay Landsman, who plays Dennis Mello and was the inspiration for the character of the same name.
In season one, two detectives, Augustus Polk and Patrick Mahon - were assigned to the Barksdale detail. The names "Polk" and "Mahon" are a play on "pogue mahone," the anglicized version of an Irish expression meaning "kiss my ass." "Pogue Mahone" was also the original name of British folk-punk band The Pogues, whose music is used throughout the series.
Tom Waits - composer of the show's title theme, 'Way Down In The Hole' - agreed that The Wire's producers could make use of the song provided they first let him see the show. Videotapes were promptly dispatched to the Waits household, followed by weeks of agonising silence. When the execs finally got the courage to give the legendary singer-songwriter a call, Mr Waits explained that he'd received the cassettes but he couldn't play them because he didn't know how to operate his VCR. "My wife knows how to use it and she'll be back in a couple of days," Waits continued. Two days later, a release was signed.
Much like its sister show Homicide: Life on the Street (1993), contains numerous references to David Simon's book "Homicide: A Year On The Killing Streets". For instance, the opening of the very first show is lifted directly from the book.
Marlo Stanfield was based on Timmirror Stanfield, a major Baltimore drug trafficker. In 1986, Stanfield was 25 and ran a gang which included over fifty members. The Stanfield gang controlled South Baltimore's Westport area and West Baltimore's Murphy Homes housing project. The gang committed multiple murders and drew the attention of authorities, who were able to persuade fifteen witnesses to testify. The core of the gang was convicted.
The journalist characters of the fifth season were mostly based on real-life employees of The Baltimore Sun during David Simon's tenure as a writer for the newspaper. Scott Templeton is based on Jim Haner, a Sun reporter whom Simon believes fabricated stories. James Whiting is based on former Sun editor John Carroll. Thomas Klebanow is based on former Sun editor Bill Marimow. Rebecca Corbett, Tim Phelps, Steven Luxenberg, and Jay Spry are all based on former co-workers with the same names. Staff writer William F. Zorzi, a former Sun reporter, plays himself. Simon based Gus Haynes on himself.
At a reunion of some of the cast in 2014, it was revealed that the actors weren't all that satisfied with the show at first. "I told my agent to call Law & Order (1990)," said Wendell Pierce; Sonja Sohn said, "A lot of us were like, 'I don't know, it's kind of slow.'"
Stringer's name is a composite of two real Baltimore drug lords, Stringer Reed and Roland Bell. His story bears many similarities to the life of Kenneth A. Jackson-specifically, his crossover from the illegal drug trade to legitimate business ownership and political contributions.
Michael B. Jordan did little preparation for the part of Wallace, but used his experiences growing up on the streets of Newark, New Jersey, as a way to prepare for the role. Jordan said, "I live in an area where there are lots of drug dealers and I know some people who may or may not sell drugs, so this is not new to me."
Sonja Sohn would gather relevant members of the cast to memorialise any character who was killed off. This began after she learned she was supposed to be killed off and fought for her character's life.
Domenick Lombardozzi speaks with the accent of his native South Bronx, which producers did not believe Lombardozzi would be able to convincingly hide and so did not ask him to try, planning a future explanation as to why the character was policing in Baltimore. Ultimately, in the fifth season premiere episode, "More with Less", Herc mentions having come from the Bronx when he makes a reference to his hometown New York Yankees being historically more successful than the Baltimore Orioles.
Rawls' distinctive manner of intimidating subordinates is based on real-life Baltimore CID commander Joe Cooke. David Simon has also commented that Rawls' attitude towards the murder rate and his unit's clearance record is a product of the extreme pressure he is under
Michael Kenneth Williams has stated that he pursued the role of Omar because he felt it would make him stand out from other African Americans from Brooklyn with acting talent because of its contradictory nature.
Bubbles was based on a real police informant known as "Possum", whose true identity has not been made public at the request of his family. Possum was noted as having an incredible memory for faces, and was often very helpful in pointing out drug dealers to police. David Simon met with him twice, shortly before Possum's death from AIDS, intending to write an article about him. He ended up turning it into an obituary.
'David Simon' (II)'s books "Homicide: A Year on the Killing Streets" and "The Corner" (written with Ed Burns) both mention the real Dennis Wise. He is described as one of the two most infamous contract killers active in Baltimore during the late 1970s - Vernon Collins being the other. Police were frustrated by the fact that no witnesses could be found against either man. Neither Wise nor Collins would break under intense police questioning, refusing to say anything other than to request a lawyer. Dennis Wise was eventually sentenced to life in prison in 1979 for a contract killing. He earned his bachelor's degree in Psychology while in prison. In 1999, Maryland Correctional officials transferred Wise to an Arizona prison in Yuma because he was allegedly leading an influential prison gang. Wise wrote a novel called The Wolf Trap while in prison.
In an online interview, David Simon stated that Ziggy is loosely based on a real stevedore named Pinkie Bannion whose antics have become a local legend around the docks. According to Simon, Bannion "used to take his duck to the bar and repeatedly expose 'pretty boy' and all else. As they said in Bawlmer about Pinkie: 'That boy ain't right.'"
James Ransone, is a Baltimore native and has described Ziggy as representative of the difficulties people face just trying to get by in Baltimore. The character's creators have deemed him "the angry prince of goofs."
Due to the fact they hadn't appeared in anything significant until The Wire, and their American accents were so perfect in the show, many people were unaware that Idris Elba and Dominic West were actually British.
David J. Smolar, who appears in the final episode of season 3 as a reporter talking to Councilman Gray, previously appeared as the piano player in a restaurant scene between D'Angelo and his girlfriend in episode 5 of season 1. Smolar performed the piano music heard in that episode, a posthumous Chopin Etude and later movement 2 of Beethoven's Pathetique Sonata.
Michael Kenneth Williams expressed that his relationship with and love of off-Broadway New York theatres, such as the National Black Theater in Harlem gave him the skill set needed for his portrayal of Omar; in particular using the Meisner technique to create Omar from the ground up, immersing himself by researching details of inner city Baltimore. The role presented a particular challenge as it was the first major recurring television character he had played.
David Simon has said that Omar is based on Shorty Boyd, Donnie Andrews, Ferdinand Harvin, Billy Outlaw and Anthony Hollie, Baltimore stickup men between the 1980s and early 2000s who robbed drug dealers. Donnie Andrews later reformed, got married and helped troubled youths. In season 4 of The Wire he plays one of the two men Butchie sends to help Omar in prison, in the episodes "Margin of Error" and "Unto Others" and Omar later meets up with him at Blind Butchie's in "That's Got His Own" while planning the big drug robbery. Andrews died at age 58 in New York City on December 13, 2012 after suffering an aortic dissection.
George Pelecanos is given credit with creating the character of Dennis Wise, based on unused notes from his novel "Drama City", about a man getting out of prison after almost two decades. The idea reflected the "reform" theme of the third season, so the character was added.
Jamie Hector has commented that he sees Marlo Stanfield as striving to obtain power rather than profit and revelling in using that power over others and that much of his performance stems from trying to capture Stanfield as a man of power and economy using minimalist movement and speech.
Wee-Bey Brice was based on a hitman named Vernon Collins, AKA Bey-Brother, who worked for a heroin dealer named Thomas H. Taylor. He was described by one FBI informant as a "narcotics hit man who is feared throughout the narcotics underworld in Baltimore." Collins is mentioned in David Simon's book "Homicide: A Year on the Killing Streets" as one of Baltimore's notorious contract killers in the late 1970s along with Dennis Wise (who spawned a character of the same name.) Wee-Bey is a reference to this hit man and drug trafficker. Collins was arrested in 1987 and sentenced to thirty-five years in prison.
Michael B. Jordan auditioned before The Wire casting director Alexa Fogel in New York City for the role of Bodie. He was called back twice and the auditions went well, but he was turned down for the part because Fogel thought he was too young. The part went to Jordan's friend J.D. Williams, who grew up in the same hometown with Jordan in Newark, New Jersey.
David Simon has said that Clay Davis is based on three different politicians in the Maryland State Senate, and that his affectionate use of the word "partner" is based on one of them, saying that everybody in Baltimore knows who this is.
A fictionalized version of the events of the 1999 Baltimore mayoral election were presented in third and fourth seasons. Many saw the connection between Carcetti and Martin O'Malley, an Irish-American Baltimore City Councillor who was elected mayor, defeating two African American opponents. David Simon denied that the character of Tommy Carcetti was supposed to be O'Malley. David Simon did acknowledge that O'Malley was "one of several inspirations" for Carcetti. He further stated that while Carcetti was "reflective" of O'Malley, Carcetti was a composite drawing aspects from other local politicians that he had covered when he worked as a reporter for The Baltimore Sun.
David Simon said that Avon Barksdale is a composite of various Baltimore drug dealers. He is likely based, to some extent, on at least two notorious Baltimore drug dealers: Melvin Williams (who plays the character of The Deacon)and Nathan Barksdale.
Dominic West's original audition tape for the part was recorded with him as the sole actor leaving spaces for the lines that would be spoken back to him. The producers were amused by the tape and agreed that they had to give him an audition.
The trivia items below may give away important plot points.
In an unusual move for a police series the officers almost never fire their guns. Only one police officer, Prez, ever fires his gun on the show and in all three cases it is a mistake. The first time he accidentally shoots the squad room wall. The second time he drunkenly fires a shot into the air and then (compounding his gun mistakes) uses it to pistol whip a teenager, blinding him in one eye. The third time he mistakenly shoots an undercover cop.
In season four Dominic West, the ostensible star of the series, requested a reduced role so that he could spend more time with his family in London. On the show it was explained that Jimmy McNulty had taken a patrol job which required less strenuous work.
Although Cheese Wagstaff and Randy Wagstaff have the same last names, it is never stated that they are related. David Simon has since confirmed in interviews that Cheese is Randy's father. Simon planned to reveal this in a fifth season episode but later decided against it.
Producer Robert F. Colesberry also plays Detective Ray Cole. After Colesberry died tragically following routine heart surgery, the Ray Cole character also died from a heart related illness in the show. The entire cast participated in an elaborate detectives wake in honor of Cole and Colesberry's memory.
When John Doman found out that Rawls was gay, he went to David Simon and told him not to hold back, that he would go as far as they wanted to play that side of his character. The funny thing is that Rawls' homosexuality barely matters on the show.
