Canada's first film in the horror genre.
The first Canadian film to be widely distributed in the United States, and the only Canadian 3-D feature.
After their only 35mm print of the film was deemed too brittle to be screened again, the Toronto Intermational Film Festival partnered with The 3-D Film Archive in New Jersey and Technicolor Toronto to restore The Mask, with the new digital print debuting at TIFF in 2015.
According to a piece on the film in "Filmfax" (issue #25), Slavko Vorkapich's ideas for the 3-D sequences were ultimately too expensive to be used, and director Julian Roffman did much of the conceptual work himself. Vorkapich's name remained in the credits because of a "pay or play" option in his contract.
Was an experiment in Season 13 of Mystery Science Theater 3000 - Halloween Special in 3D
