Just as quickly as it had captured the American public's imagination during the early '50s, 3-D film was pushed into the margins during the mid-'50s and pretty much stayed there for the next three decades or so. Advances in technology that eliminated the labor-intensive step of projecting two prints simultaneously helped lead to a mild revival of the format in the '60s -- almost exclusively relegated to low-budget exploitation fare like horror and sex films.
One of the only major studio efforts to incorporate 3-D during this era was the 1961 Warner Brothers horror film The Mask, which shot four of its scenes in 3-D to enhance the psychedelic visions that the main character experienced when putting on a mystical mask.
But as the '70s dawned and pornographic cinema became increasingly chic, 3-D filmmaking largely abandoned even horror in favor of an array of hardcore and soft-core adult fare. One notable movie, 1974's Flesh for Frankenstein (AKA Andy Warhol's Frankenstein AKA Frankenstein 3-D), managed to combine the sexual content with graphic horror, gaining an X-rated cult following in the process.
But in America, such 3-D horror movies were few and far between, and the format's domestic marginalization proved to be something of a boon for foreign 3-D horror. Films like Japan's sexually-inclined ("pink film") thriller Perverted Criminal (the country's first 3-D effort), Spain's Frankenstein's Bloody Terror (starring the iconic Paul Naschy), Great Britain's The Flesh and Blood Show (which featured only one sequence in 3-D) and South Korea's infamously awful King Kong ripoff A*P*E were imported to the US, keeping the 3-D horror tradition alive until its '80s domestic revival.
