Trivia: This film was originally much longer, and the plot was quite different at times. Kevin Smith was forced to alter it after a few early negative test screenings. The original cut had a much different opening that makes no mention of Julie Dwyer's death, a number of extended scenes, and some original dialogue that was redubbed for the theatrical release. This original cut was finally made available in the 10th Anniversary Special Edition.
Trivia: The producers were so confident the film would be a hit, they even talked with Kevin Smith about a sequel. Smith conceived an idea called "Mallrats 2: 'Die Hard' in a Mall." He had also considered altering his idea for "Chasing Amy", and making it into a tamer PG-13 comedy for the studio, so it would sell better. After "Mallrats" flopped, the sequel was dropped, and Smith made "Chasing Amy" as originally envisioned.
Trivia: The studio did not want Jason Mewes to play Jay, even though the character is based on him, reasoning that Mewes wasn't a legitimate actor. Seth Green and Breckin Meyer were brought in to audition for the part. Green told Kevin Smith that he didn't want the part because he felt it belonged to Mewes. The studio agreed to let Mewes film some scenes and ended up approving his casting after Smith sent some dailies to them.
Trivia: Actress/model Jenny McCarthy had auditioned for the film (though she was not cast), and reportedly her audition went as well as any other audition, with director Kevin Smith joking with her and being polite. Some time after the audition, Smith was shocked to learn that McCarthy had begun blasting him in interviews, alleging that she was laughed at and tormented by Smith and the rest of the crew holding the auditions. While Smith was initially angry about the (allegedly) fabricated rumors, he soon forgot about it. About ten years later, he was approached by a mutual friend of he and McCarthy who wanted the three to collaborate together. Smith agreed to work with McCarthy, but was almost immediately informed she refused to work with him.
Trivia: "Walt Flanagan's dog" is mentioned in this movie and referenced in other Kevin Smith productions. When filming Mallrats, Walt Flanagan (an actor and friend of Kevin Smith) had just gotten a rambunctious puppy that destroyed Flanagan's hotel room while he was on set. It amused Kevin Smith, so he began using it as an in-joke.
Trivia: In the 2010's, Director Kevin Smith tried repeatedly to get a sequel made to "Mallrats." Originally, he was going to go with his original sequel idea from the 90's ("Mallrats 2: 'Die Hard' in a Mall"), but the film eventually became "MallBrats", a sort-of sequel that would follow a new generation of characters with the original characters in supporting roles. The sequel was eventually re-worked into an event television series that Smith was going to write and direct, before he was forced to abandon the sequel due to rights issues.
