Third Dimensional Murder

Third Dimensional Murder 1941, also known as Murder in 3D, is a 3D short comedy film produced and narrated by Pete Smith and released by MetroGoldwynMayer. This is the last of the Audioscopiks 3D short film series, after Audioscopiks 1936 and The New Audioscopiks 1938.

The third and last in the Pete Smith Audioscopiks 3D series of shorts, this film used footage shot specifically for it, unlike the previous two shorts which utilized test footage shot by Jacob Leventhal and Jack Norling.With the success of the first two shorts, Smith consulted J.M. Nikolaus in the camera department at MGM. Nikolaus went to studio manager E. J. Mannix who gave Nikolaus a budget of about 3,000 to create a stereoscopic camera rig. After some trial and error, Nickolaus created a camera using two Bell amp Howell 35mm cameras with specially matched lenses made by Bauch and Lomb. The lenses were 2inches apart and were shot into prisms. George Sidney directed the short. Sidney later directed the 3D feature for MGM, Kiss Me Kate. ........
