As an April Fool's gag this year I put together a video for some friends and colleagues with the premise that Alfred Hitchcock had at one time intended to film REAR WINDOW in 3D, and that now that his true intentions had been uncovered, a dimensionalized version of the film was in the works. Thankfully, this is not the case...but it almost seemed a plausible idea.
If you've got a 3D monitor and glasses handy, you'll be able to see some 3D footage within the video that starts at 4:19. Set the 3D mode to "Interleaved." Enjoy!
