I went and saw the movie Coraline last night and it was mind-blowing! It is the first stop-animation movie ever filmed in Stereoscopic 3D.
On a side-note I just read that TOOL is filming their latest music video, for the song "The Pot", using this same technique! Awesomeness.
How they do it :: Circularly Polarized Glasses
To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through circular polarizing filters of opposite handedness. The viewer wears low-cost eyeglasses which contain a pair of analyzing filters (circular polarizers mounted in reverse) of opposite handedness. Light that is left-circularly polarized is extinguished by the right-handed analyzer; while right-circularly polarized light is extinguished by the left-handed analyzer. The result is similar to that of steroscopic viewing using linearly polarized glasses; except the viewer can tilt his head and still maintain left/right separation.
Real D Cinema System (used recently with the stereoscopic Disney movie, "Chicken Little 3D") uses electronically driven circular polarizers that alternate between left- and right- handedness, and does so in sync with the left or right image being displayed by the (digital) movie projector.
