Rider Strong claimed that he loved the leather jacket he wore on the show so much that he didn't want to return it to Disney when the series was over. He took it with him to New York when he went to school but it was stolen out of his car in Brooklyn. Instead of giving it back, he switched it out with another jacket and Disney had no idea.
The character of Topanga was originally just a fringe character, a kind of hippie new-age girl intended as a foil to the main characters. But she proved so popular that the producers expanded her character to become more mainstream and, eventually, a main player in the series and the love interest of Cory Matthews.
Occurring around the fifth season of the show, Rider Strong wanted to quit simply because he wanted to go to college. Michael Jacobs told him that they could work out a schedule so that he can go to college, and he did.
In the first season, the creators and writers of the show wanted to give Cory a second best friend along with Shawn but none of the child actors they tried stuck. The various child actors they tried always had the same assigned chair at the end of the table on the John Adams Middle School cafeteria set. Because of the revolving door of child actors the show went through trying to fill that role, the cast came to jokingly refer to that chair as "the death chair".
Danielle Fishel was originally cast as a guest star on the pilot. The actress who was cast as Topanga wasn't working out, so Danielle and another girl were asked to read on the spot. Danielle won the role.
In episode 119, "Kid Gloves", we see Cory scuba diving in the school pool from his point of view, and then come up to the surface to see Mr. Feeny looking down on him. This mimicks a scene in The Graduate (1967) in which Dustin Hoffman's character comes up from scuba diving to see his father looking down on him who, like Mr. Feeny, is also played by William Daniels.
Danielle Fishel claims that producer Michael Jacobs named her character after Topanga Canyon in Los Angeles. Jacobs was driving past that location, when production called and asked for a name for the character. Jacobs admitted that if he drove any further when the call came, he would have named the character Canoga.
In the series finale Cory talks to his little brother Joshua, played by Daniel Jacobs. Earlier in the season, Daniel Jacobs played the little boy standing in the hallway when Topanga and Cory move into their apartment in "The Honeymoon is Over"
The real ages of all the characters who end up in college together (Cory, Eric, Topanga, Shawn, and Jack) differ from just a few years apart between each other except Angela, played by Trina McGee, who is actually the oldest of them all. However, in the show Eric and Jack are supposedly seniors in college while Cory, Topanga, Shawn, and Angela get into college at the same time, which states that they're all probably the same age. Trina McGee is in fact 10 years older than Rider Strong and seven years older than Will Friedle, who plays Eric, while Jack (Matthew Lawrence) and Cory (Ben Savage) are actually the same age in real life.
The syndication of "Boy Meets World" was so successful that ABC Family started to air it twice during its daytime and evening schedule (2014). MTV2 also airs the show on weekends (2014). A June 2014 prime-time airing of the show on Disney Channel registered 1.825 million viewers according to a report.
In the beginning of the show, Shawn mentions he has a sister who helped with the straightening of Cory's hair in one of the episodes. However, later on in the series, Shawn doesn't have a sister. In interviews, Rider Strong explained that those lines were supposed to be attributed to one of the many kids they attempted to make Cory's second best friend but was fired in the filming process. In the haste to get the episode filmed, the writers just gave those lines to Shawn.
In the episode in which Topanga runs away from home, her Aunt Prudence comes to collect her. She tells Cory that her aunt has never been in love and wouldn't even know who Romeo and Juliet are. Her aunt is played by Olivia Hussey, who played Juliet in Franco Zeffirelli's Romeo and Juliet (1968).
Cast held a 2013 ATX Television festival reunion 20 years after the show debut on ABC. Attending the Austin reunion was Ben Savage, Rider Strong, Matthew Lawrence, Betsy Randle, Lily Nicksay, Trina McGee, and Maitland Ward.
Throughout the first season the writers were attempting to establish Cory as having two male best friends. Ultimately they were unsuccessful. This is why each episode during that time featured a different friend until the introduction of Topanga in Boy Meets World: Cory's Alternative Friends (1993).
Harry Barandes was originally cast as Eric Matthews, and Matt McCoy was originally cast as Alan Matthews, but after the pilot was shot, their scenes were replaced by Will Friedle and William Russ, who both lasted for duration of the series. A VHS tape of the original version exists.
The character 'Dana Pruitt' was a tribute to actress Dayna Price, who was an avid fan of the show and frequently visited the set in addition to her two guest appearances. Ironically, the role of 'Dana' was played by 'Larissa Oleynik', who starred on The Secret World of Alex Mack (1994)', on which the real-life Dayna was a recurring character.
Blake Soper (now Blake Sennett) who played Joey "The Rat" Epstein in many episodes, later went on to co-front the very successful Los Angeles band Rilo Kiley (with fellow child actor Jenny Lewis (Troop Beverly Hills (1989) among other projects), as well as his own breakaway band the Elected.
While some characters in the series are portrayed by different actors (such as Topanga's parents), some actors portray multiple characters. Herschel Sparber first appears in episode 2.10 (Sister Theresa) as a delivery guy who delivers gifts from TK to Cory. He then appears later that season as Shawn's Uncle Mike in "By Hook or by Crook," and then later makes his last appearance as Uncle Mike in Season 3 ("The Pink Flamingo Kid"). Julius Carry first makes his appearance in season 5 as a college professor of a class that Shawn is taking while still in high school but then reappears as Angela's father first in season 6 and then later in season 7. Thirdly, Phil Leeds makes three appearances as a minor character, first in the season 4 premiere as the guy at the truck stop who says, "I was only three hours from home"; secondly as the game show announcer on an episode later in season 4 (the only episode where his character's name is not Phil); and, lastly, he appears in season 5 as the manager of the mail room in which Cory and Shawn work. Also, Willie Garson appears first twice as Leonard Spinelli, Alan's assistance manager, then as Mervyn, who applies for a job at the store Alan opens, and lastly, as the minister who marries Cory and Topanga. He later appears as Topanga's boss in Girl Meets World.
