Here’s a red/green 3-D image from The Command (1954) which was shot in two separate versions (with completely different takes and compositions) — 3-D non-anamorphic 1.85:1 widescreen and CinemaScope anamorphic 2.55:1 (2-D) widescreen.
The Command was only released to theaters flat, usually in CineamScope. The left side of the 3-D negative was edited and used for the flat release and 16mm prints. If the right side is still around, a 3-D release is possible! (Let’s hope!)
The Warner Archive DVD of The Command presents the CinemaScope version. It’d be great to see this make it to Blu-Ray, especially if the 3-D could be worked out. And while you’re at it Warner Archive, how about The Bounty Hunter (1954)?
