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.
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.
According to the show's website, John Stamos, Dave Coulier and Jodie Sweetin are the only cast members to appear in all 193 episodes (including unaired pilot, which is the episode that excludes Bob Saget, who otherwise is in the remaining episodes) of the series.
Full House is coming back as a Netflix Original in 2016. It will contain all of the characters from the original except the Olson twins. It will have 13 episodes and DJ, Stephanie, and Kimmy will be in all thirteen while the others will be spread out throughout the season
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).
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.
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.
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.
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.
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" (which he does with sign language), D.J.'s is "Oh, my lanta", Stephanie's is (3 catchphrases) "how rude", "hot dog" and "well pin a rose on your nose", Michelle's is (4 catchphrases and has the most), "you got it, dude", "oh, pa-lease", "you're in big trouble, mister" and "duh" and Kimmy's is hola, Tanner-renos".
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).
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.
As of 2016, "Full House" remains only one out of three former TGIF sitcoms to have had its entire series released on DVD. "Boy Meets World" and "Dinosaurs" are the only other TGIF sitcoms to have seen a full DVD release.
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 alcove of Danny Tanner's house.
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 morning show) and sharing many more scenes on the show together.
In the film Dumb and Dumber two (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.
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.
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.
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.
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" and "duh"
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.
