This one's a real head scratcher: It's a flipper- Full Screen on one side, widescreen on the other. On the box it states: Full Screen: Modified to Fit Your Screen 1.66:1 Widescreen: Anamorphic Widescreen 2.35:1 In reality the Full Screen size appears to be 4:3, while the widescreen size appears to 1.66:1. On top of that, IMDB (yes, I know they are often wrong) states the OAR is 1.78:1 and the trailer on the DVD is 1.78. What gives FOX? PS- Great movie, some might say the 2nd best Robin. Be sure to pick it up.
