Radio-Mania

Originally released as "The Man From M.A.R.S.", on December 27, 1922 at the Selwyn Theatre in New York City. It was the first feature film to use the alternate-frame sequencing form of film projection to achieve a true stereoscopic 3D image,(somewhat similar to today's field sequential 3-D). This early 3D system was called, the Teleview system, and it was invented by William Cassidy and Laurens Hammond, the man who would later invent the Hammond organ. The film met with critical success, but the technology was so far ahead of its time and the expense of installing two interlocked projectors was such, that the system met with a premature end. The film was later re-cut and re-released in regular 2D as "Radio-Mania".
