Sidney Pink, a movie producer who pioneered 3-D feature-length movies in the 1950s, died Oct. 13 at his home in Pompano Beach, Fla., after a long illness, the Los Angeles Times reported. He was 86. In 1959, Pink co-wrote and produced The Angry Red Planet, the tale of the first expedition to Mars. The SF movie was filmed in what was advertised as a “revolutionary” process called “Cinemagic,” a printing-process technique that gave the Mars scenes a pink glow, the newspaper reported.
