The Mask (re-released as Eyes of Hell and The Spooky Movie Show) is a 1961 Canadian surrealist horror film produced in 3-D by Warner Bros.

The story concerns a psychiatrist, Dr. Allen Barnes, who obtains a mysterious ancient tribal mask after one of his patients, Radin, committed suicide.

Whenever he puts on the mask, Barnes experiences dream-like visions that become increasingly disturbing and violent and even physically harm his girlfriend Pam.

Frank Taubes and Sandy Haber, two New York advertisers, proposed to Roffman and Taylor, without a script, a 2D film with 3D sequences.

Taubes and Haber produced test footage for the film, but Roffman was unimpressed and stated that their 3D effects were "crap".

[1][2] Raymond Spottiswoode, a friend of Roffman, developed a 3D system called Depth Dimension while working for the United Kingdom National Research Council and The Mask was the first film to use it.

Vorkapich's ideas required tanks of black ink, thousands of frogs, and large amounts of mice.

Wuetrich was a storyboard artist and drew many of the ideas, including ones that were not filmed such as a scene of giant spiders attacking the protagonist.

Roffman's son Peter stated that Warner Bros.' accounting prevented them from receiving profits from the film's American release.

[16] In retrospective reviews, Time Out panned the film, deeming it "a bland and hackneyed murder mystery that was spiced up by surreal nightmare sequences" and "tacky" use of 3D.

[24] Brad Wheeler of The Globe and Mail gave the film one out of four stars, similarly criticizing its 3D and plot and stating that its appeal was "limited to genre fetishists and popcorn-chomping ironists".

[25] Conversely, Chris Coffel of Bloody Disgusting felt that, despite a thin story, the film's psychedelic visuals, makeup effects and set pieces made it an enjoyable B-movie in the vein of William Castle.
