Rehassed films in stereo NO! NO! NO! If clash of the titans (and last Air bender) are anything to go by that is a big DO NOT WANT!

Older games work in stereo (see the Nvidia stereo 3d on the PC), but then the effects in a way where always there. Oh and Nintendo have shown off a stereo system that won't require any glasses (see the news about the new 3DS).
