In 1952, as television began to steal cinema audiences, Hollywood looked for a gimmick that small screens couldn't replicate. The result was 'Bwana Devil,' the first-ever feature-length 3D film in color. Using the 'Natural Vision' system, the film required audiences to wear polarized glasses to see images 'leap' off the screen. Based on the true story of the Tsavo man-eating lions, the film was a critical failure but a massive box-office hit. It sparked a 3D craze that lasted from 1952 to 1954, leading to classics like 'House of Wax' and Hitchcock’s 'Dial M for Murder.' However, the technology was plagued by technical issues; if the two projectors weren't perfectly synchronized, it caused severe headaches for viewers. The fad died out quickly, only to be resurrected decades later with the digital revolution of the 21st century.
