By the age of six, Mary-Kate Olsen and Ashley Olsen, the twins who shared the role of Michelle, started to look so different that most audiences could tell them apart. It was considered to chose one twin over the other, and have just Mary-Kate Olsen play the role. However, their fan base at the time was so huge, and co-star John Stamos didn't want one twin to leave the show, so both girls were kept in the role.
With the exception of Danny, Steve and Rebecca, all the other characters have catchphrases. Jesse's is "Have Mercy", Joey's is "cut it out", D.J.'s is "Oh, my Lanta", Stephanie's are (3 catchphrases) "how rude", "hot dog" and "well pin a rose on your nose", Michelle's are (has 4 catchphrases and has the most), "you got it, dude", "oh, pa-lease", "you're in big trouble, mister" and "duh". Kimmy's are "Hola, Tanner-Ritos", Hola Mr T and other similar phrases.
At no point in the series do we ever see Kimmy or Steve's family even though they are mentioned, Kimmy's brother is later seen in Fuller House. His name was however changed from Garth to Jimmy or it is possible that Kimmy has two brothers.
At first, the producers didn't want people to know that Michelle was played by twins, so in the beginning, they were credited as Mary-Kate Ashley Olsen. In the last season, they were credited as Mary-Kate Olsen and Ashley Olsen.
Whenever the cameras weren't rolling, Bob Saget, who is known for his raunchy adult stand-up jokes, would often get in trouble for swearing and making inappropriate jokes, even when around the child actors.
According to the show's website, John Stamos, Dave Coulier and Jodie Sweetin are the only cast members to appear in all 193 episodes of the series. Bob Saget did appear in all 192 official episodes, but did not appear in the unaired pilot. Candace Cameron Bure only did not appear in the sixth season episode "Subterranean Graduation Blues". Some episodes had just Mary-Kate playing Michelle, not Ashley and vice versa.
In the first season, Jesse's last name was Cochran, but in the second season it was changed to Katsopolis because of John Stamos' Greek heritage. The reason for the change was addressed within the series in an episode in that the last name "Cochran" was a pseudonym Jesse was using to make his name sound more like a rock star.
Sensing some awkwardness with one another, Bob Saget, John Stamos and Dave Coulier went on a road trip to Las Vegas after the first season ended to help develop chemistry, in particular with Stamos, since Saget and Coulier were friends prior to the show. Stamos and Coulier, both single at the time, really bonded during the trip and went on double dates together, while Saget, married at the time, stayed behind. The result was Stamos and Coulier becoming good friends and the writers incorporating this new dynamic in future seasons, with the two working together (first in advertising, later as a radio evening show) and sharing many more scenes on the show together.
While a number of blooper reels were shown on TV show compilations, a rough quality tape was leaked on the internet. The video prominently consists of some cast members accidentally swearing during taping.
Bob Saget and Dave Coulier became friends through the L.A. Comedy circuit and Coulier lived on Saget's couch in his early days as a comedian, similar to struggling comedian Joey Gladstone living in the basement of Danny Tanner's house.
The show initially was going to have a ninth season. However, the ninth season was to be on the (then) new WB Network as an old, "classic" show to help launch the new network and lineup. John Stamos (Jesse) did not like how the show was being dropped from ABC, a top three network, and moving to a fledgling new network and announced that the eighth season would be his last. Candace Cameron Bure (D.J.) also planned on the eighth season as her last, doing sporadic guest appearances during the ninth season as her character D.J. came home to visit from college during the holidays, as Cameron in real life was planning on going to college after season eight. After these two announced their departures, the others decided that it was time to call it quits, and the writers decided the series had gone as far as it could go, and the eighth season on ABC (1994-1995) ended up being the final season for Full House (1987).
Mary Kate and Ashley Olsen nearly left the show after the first season because their real-life mother was concerned about them missing out on having a "normal" childhood. After a significant raise in salary from the show's producers, she agreed to let them continue. Their mother also let them stay due to the fact that they became so popular.
The Olsen twins renegotiated their contract in 1990 to a much higher amount than the rest of the cast. It also allowed them the freedom to do endorsements and other media opportunities while still working on the show.
According to frequent director Joel Zwick, filming of the two-part episode in Disney World became a problem for Jodie Sweetin, as she was bombarded by fans and photographers, some of whom even followed her into the bathroom.
Danny Tanner didn't get obsessed with cleaning until season 2, but it's played as if he was always that way. This contradicts the entire first season especially episode 4 of season one, "The Return of Grandma", in which the guys have to prove to Danny's mother that they can keep the house in order. Danny is just as clueless about cleaning as the other men.
In the episode "Stephanie Plays the Field" there's a part when Michelle visits Jesse and Becky in the attic but when they ask to be alone Michelle spins around. While doing this you can hear someone say "but you are alone silly" followed by Michelle saying this line. This was because a person would stand behind the cameras telling Michelle her lines while she was on set filming.
The original premise of the show was three single stand-up comedians living together and the theme was more of an adult-oriented sitcom titled "House of Comics". However, with shows like The Cosby Show (1984) and Family Ties (1982) doing well with family-oriented themes, the show was changed to incorporate family morals and values and the name was changed to Full House (1987).
In the first episode, D.J. says Kimmy has three sisters. In later seasons, Kimmy says she has one older brother named Garth. On the spin off series, Fuller House (2016), she has a younger brother named Jimmy.
Bob Saget and Paul Reiser were on the top of show creator Jeff Franklin's list to play the role of Danny Tanner, but at the time Saget was under contract for The Morning Program (1987) on CBS and Reiser opted for the role of Michael Taylor on My Two Dads (1987). Eventually Saget became available and he got the role immediately.
In the film Dumb and Dumber To (2014), Harry tells Lloyd, (listing his sacrifices over his achievements in their lifetime friendship) that he's watched every episode of 'Full House' (1989). This was a real life jab at actor Jeff Daniels-as fans have often mistaken him for series star Dave Coulier.
As of 2016, 'Full House (TV Series 1987-1995)' remains only one out of four former TGIF sitcoms to have had its entire series released on DVD. Boy Meets World, 'Dinosaurs (TV Series 1991-1994)', and 'Sabrina the Teenage Witch' are the only other TGIF shows to have seen a full DVD release.
It's often been felt by older viewers that Danny is too young to be D.J.'s father (hearing the dialogue and doing the math he was 19 when she was born). Though, young men around the time of the '70s were actually fathering children when they were in their late-teens, early-twenties (Tom Hanks being one of them).
Initial title of the show was "House of Comics" due to stand up comedians Bob Saget and Dave Coulier living in the house. Decided to change it to Full House (1987) when it was realized it was more a family-orientated show.
Throughout the series Joey is wearing Detroit area sports merchandise or has Detroit sports teams memorabilia hanging on his wall. Dave Coulier is from the Detroit area and is a huge fan of the Red Wings, Tigers, Pistons, and Lions. In an interview he did before the 2012 World Series he said that "Joey would pull for the Giants while Dave is pulling for the Tigers".
Uncle Jesse's mother is played by two different actresses in the series. On Season 1, Episode 4 Jesse's mother comes to help clean up the house. In all the other Seasons it's a different actress as Jesse's mother.
Character Catchphrases Jesse - "have mercy" Joey - "cut it out" Stephanie - "how rude" and "well pin a rose on your nose" D.J. - "oh my lanta" Michelle - "you got it dude" "you're in big trouble mister", "duh" and "oh puh-leeze." Danny is the only main character to never have a catchphrase.
Throughout season 2 and select episodes of season 3, Joey is wearing a University of Michigan hockey jersey. In real life Dave Coulier attended the University of Michigan for a year before dropping out to pursue comedy full time.
Two Freddy Krueger references were made - once, when Kimmy put DJs face on Freddy Krueger's body when she wrote for the school paper; the other was when Joey referred to himself as a bad guy and Danny said, "Freddy Krueger is a bad guy." Coincidentally, Walter was featured in "A Nightmare on Elm Street 5" and Aaron was featured in "Wes Craven's New Nightmare."
Joey wears an old English "D" Detroit Tigers hat in a few episodes and wears several Tigers throwback jerseys in the series. He also wears a "Bad Boy" era Detroit Tigers t shirt under a long sleeved shirt in a few episodes in season 4.
Series regulars Scott Weinger and Gail Edwards had previously appeared together on another Miller-Boyett series, The Family Man (1990). Weinger had a regular role as the oldest son and Edwards had a recurring one as the single mother of Weinger's brother's friend.
Andre "Rosey" Brown played two different roles on two episodes, The Day of the Rhino as a security guard and on Super Bowl Funday as Weeb, the owner of a sports bar that Joey, Jesse, and the kids visit.
Nancy Dussault and Lydia Cornell both guest starred in Full house but not in the same episode with Lydia Cornell guest starring in season 2 in the episode entitled El Problema Grande de DJ and Nancy Dussault in season 3 entitled Aftershocks
In the first season Stephanie has pierced ears. But later in the series there is an episode where Stephanie pierced her own ears because Danny isn't fine with the idea that she will let her get her ears pierced at her age.
