The first five episodes of the series were filmed in Georgia, before filming moved to the Warner Brothers set in Burbank, California, where filming stayed for the rest of the series. The original Georgia locations are to this day often visited by Dukes fans.
They crashed a lot of cars filming this show. Replacing the police sedans was easy - replacing the old Dodge Chargers ("General Lee") was not as they weren't made anymore. It got to the point where producers would spot a Charger on the street and would approach the owner and offer to buy it on the spot.
Somewhere between 256-321 "General Lee" cars were created and mostly destroyed during the series. Less than 20 in various states of disrepair still exist. Despite popular belief, there were no 1970 Chargers used in the series according to all the car builders.
Bo and Luke used bows and arrows instead of guns because the boys were on probation for moonshine running and any use of firearms would be seen as a probation violation.
Boss Hogg had a twin brother (Sorrell Booke in a dual role), who appeared just once in The Dukes of Hazzard: Baa, Baa White Sheep. He was the literal opposite of Jefferson Davis Hogg - he was completely law-abiding, wore black, and his name was Abraham Lincoln Hogg.
The name of the state that Hazzard County was in was never explicitly revealed. However, it was within driving distance of Atlanta, Georgia and in The Dukes of Hazzard: Happy Birthday, General Lee Boss Hogg tells Daisy she has "the best legs in all of Georgia".
When Tom Wopat and John Schneider briefly left the show during their contract dispute, their absences were explained by having Bo and Luke leaving Hazzard to try their hands on the NASCAR circuit.
The original Georgia location of Ace's Used Car Lot (Repo Men episode) was torn down in 1998 to make way for a church expansion, and the original Boar's Nest is also now a church.
The General Lee's famous "Dixie" horn wasn't originally planned; when the producers were driving in Atlanta during the first few episodes, they heard a car pass with a "Dixie" horn and chased the driver down and convinced him to sell the horn. They later realized that it was a novelty horn which could be purchased at any auto parts store for a third of what they paid for it. The horn was only used in the first five episodes. Once filming moved to the Warner Brothers lot, the horn was edited in during post-production.
During the 1981-82 season, John Schneider and Tom Wopat demanded raises, claiming that they were owed a lot of royalties from the show's extensive line of merchandise. They ended up walking out, and the producers replaced the characters of Bo and Luke with Coy and Vance for the 1982-83 season, which resulted in a big fall in the show's ratings. The dispute with Schneider and Wopat was eventually settled, and they returned for the final four episodes of the season, with the "clone" Dukes being written out in the same episode, never to be mentioned again.
During season two, Ben Jones walked off the set over a dispute over whether or not he should cut his hair and shave. He was replaced temporarily by Cooter's cousins B.B. Davenport, played by Mickey Jones, and Ernie Lively, as L.B. Davenport.
James Best also left the series temporarily during season two over a dispute regarding the dressing rooms. He was replaced by Jeff Altman as Hughie Hogg, followed by Clifton James as Lester Crabb, Dick Sargent as Grady Byrd, and James Hampton as Buster Moon. Altman and James were listed as guest stars, while Byrd and Hampton were actually listed in the opening credits.
Sonny Shroyer had it written into his contract that if his spin-off, Enos, didn't last a full season, he could return to The Dukes of Hazzard. Enos only lasted 17 episodes, after which Shroyer returned to the Dukes.
On the CMT "Inside the Dukes" special, Catherine Bach said she offered to walk out along with Tom Wopat and John Schneider, but they convinced her to stay, with Uncle Jesse. The reasoning was that if she left, then there would be no show to come back to.
Country singer Mel Tillis played a character in one of the episodes, and then later reappeared in another episode as himself, who was a victim of Rosco's "Celebrity Speed Trap."
Sorrell Booke had it in his contract that there must be things that Boss Hogg would not do. The two things he would not do were dealing drugs, and killing.
In several interviews, John Schneider said that he lied about his age in order to get the part of Bo Duke. He told them that he was 24, when in reality, he was only 19. He also showed up in a T-shirt and blue jeans, carrying a six pack of beer, and pretending to speak with a Southern accent, when in reality he was from New York City.
According to the "Unofficial Guide to The Dukes of Hazzard book, Gy Waldron wanted Hazzard "to be in a location like Chatsworth, Georgia." Chatsworth is in northwest Georgia in Murray County, and does have a strong "bootlegging" history.
According to Catherine Bach in an interview on E! True Hollywood Story, her famous "Daisy Duke" shorts almost didn't make it onto the show. When network executives saw her wearing the shorts, they had a fit and told the producers she couldn't wear them. After arguing back and forth, the execs allowed her to wear them on one condition: she had to wear pantyhose beneath them so nothing would accidentally be revealed. Instead of diverting attention from her outfit, as the execs hoped, the hose highlighted her long, shapely legs, making Bach a '70s TV sex symbol.
The "General Lee" is a 1969 Dodge Charger. 1968 Chargers were also used, but their round tail lights and front grill were replaced from those on the 1969 model on the otherwise nearly identical model years.
James Best based the "coo coo" sound that Rosco made whenever he got excited on noises he used to make when he played with his children. He did this to make Rosco more childlike and therefore less of a threat to the Dukes.
J.D. Hogg's official government title is County Commissioner. Among his appointed duties is to assess and allocate county funding for whatever Hazzard County needs such as funding the police department, road repair/work, and providing funds for other government run operations/departments. Of course, being crooked, Hogg uses the funds to finance his illegal operations.
J.D. Hogg's nickname of "Boss" and his shady dealings and criminal activities are a reference (albeit a comical one) to what is known as the "Southern Fried Mafia". Unlike major criminal organizations (like the Italian Mafia, Japanese Yakuza, Russian "Red" Mafya, etc.) which control criminal operations on a national or international level, the Southern Fried Mafia controls criminal activities such as gambling, prostitution, and distilling and bootlegging moonshine (in dry counties or states) on a smaller level wherever they can corrupt officials (like Sheriff Roscoe P. Coltrane) in small towns and Southern cities (like Atlanta, Mobile, Montgomery, Memphis, etc.). A more serious example of this criminal group's function can be seen in films like White Lightning and Walking Tall.
J.D. Hogg's last name may or may not have been inspired by Texas Governor Jim Hogg. Incidentally, Jim Hogg had a daughter named Ima Hogg (as in "I am a hog").
Houston, TX rapper Slim Thug was nicknamed Boss Hogg since he usually drove a Cadillac convertible; the namesake later became the name of a rapper's collective known as the Boss Hogg Outlaws. The slang 'Boss Hogg' in the Houston, TX hip-hop scene, is a 1969-76 Cadillac DeVille or Eldorado convertible (during the TV series, J.D. Hogg's convertible was a 1970 Cadillac DeVille).
There were many life-not-imitating-art aspects to Sorrell Booke's casting as J.D. Hogg. Hogg was a stupid man, while Booke was an Ivy League graduate who spoke several languages fluently and had done military intelligence work during the Korean War. The character was cartoonish, while Booke was well-established as a serious actor before accepting the role. Hogg is grotesquely overweight, and Booke in real life had to wear a huge fat suit to achieve the comedic dimensions sought. And while Hogg was a rightfully hated fictional character, Booke was well-liked by the cast and crew; in fact, the 1997 reunion movie came about after the main cast members went to Booke's funeral in 1994 and ended up talking to each other afterwards.
Extremely short, form-fitting, denim cut-off shorts worn by women are often referred to as "Daisy Dukes" referencing the character from this show, which popularized this item of clothing.
When Sonny Shroyer returned a year after the cancellation of Enos, his replacement Rick Hurst continued his role as Deputy Cletus. Midway through that season, Hurst left when cast for the short lived series Amanda's, and Cletus disappeared from the show without explanation. Hurst would not play the role again until the reunion movies.
The show's theme Good Old Boys by Waylon Jennings was released as a single in August, 1980. The single version had an extra verse, and an extended musical bridge midway through the song. The song peaked at Number 21 on the Billboard Pop Chart, and hit Number One on the Country Chart.
The casting of Don Pedro Colley in the recurring role of Sheriff Little was intended to bring racial diversity to the series. Producers intentionally cast African American Actors for key or prominent guest roles for the same purpose.
The series aired three two hour TV movies, which originally aired as part of CBS's Movie of the Week. All three were each re-edited as two part episodes when the series was sold into syndication.
Enos and Cooter were the only regular characters with no familial relationships to any other regular on the series. (Though Cooter was an "honorary" member of the Duke family, and his cousins appeared in his place during Ben Jones walk off). Boss and Rosco were Brothers-In-Law, and Cletus was a cousin of Boss Hogg.
