As in the other Askewniverse films, the characters Jay and Silent Bob feature prominently, and characters and events from other films are discussed. Several cast members, including Jason Lee, Ben Affleck and Joey Lauren Adams, have gone on to work in several other Smith films. Comic-book icon Stan Lee appeared, as did Brian O'Halloran, the star of Smith's breakout feature Clerks.
Despite failing at the box office and receiving a lukewarm critical reception, Mallrats has since become a cult classic. Plans for a sequel film titled MallBrats were announced in March 2015. By the following year, the project had morphed into a proposed television miniseries, but by February 2017, Smith announced that he had not been able to sell the series to any network. In January 2020, Smith revealed that development on a sequel film has started again, this time under the title Twilight of the Mallrats.
