Plans for a sequel, "The Mask II", were in the works years before this film. Nintendo Power magazine held a contest, and first prize was a walk-on role in that movie. The project was canceled, and Nintendo Power issued a public apology to the contest winner in their final issue. Years later, the winner was revealed as Nathan Ryan Runk, from Arbutus, Maryland. The film was technically on hold, so Runk could have chosen the role or money and merchandise. Runk, who was 12 at the time, chose the money, and received $5,000, a film crew jacket (which he later lost), and several Super Nintendo video games, including "Pilotwings 64" on Nintendo 64. He later claimed it was "absolutely the right call."
Jamie Kennedy reportedly hated his time in Sydney filming this movie, because hardly anyone recognized him in public, and he was repeatedly turned down by local women in bars, who had no idea who he was.
