Poika ja maski

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."

When Tim plays Mario Kart: Super Circuit (2001) the sound effects are from a different game.

In non Region 1 DVDs, there is an additional scene where green sperm cells fertilize an egg.
