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 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.
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.
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.
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.
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 Scott Weinger's first appearance ("Sisters in Crime"), his name was "Steve Peters". In season six, DJ flies home from Spain with a new boyfriend she "met" through the program: Steve Hale, played again by Scott Weinger.
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.
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.
