Movies are as big as you want them to be - there's a tradeoff between quality and size. BluRay movies are often overkill using VC1 or h.264 in the range of 25mbit - you can do 1080p for your typical 90-100min movie in very nice quality 1080p in the space of a DVD, but you're at the limit - want to improve the quality beyond 10-11mbit or have a longer movie (and maintain 10-11mbit) and it will not fit. BluRay (and HD-DVD) are considerably larger and offer the flexibility to double the quality, add higher quality audio, and double the length of the film (all at the same time) and still have room to spare.
As an aside, very few games - on 360 and on PS3 - are actually rendered at 1080p. Most games are rendered around 720 - in the case of the 360 it will then scale that up using a hardware scaler. In the case of the PS3 it will actually output a 720p signal while the game is running because it does not have a hardware scaler. Video, like DVDs, can still be scaled up using the GPU on a PS3 - this is impractical during games because the games need all the GPU's capabilities themselves. The idea of the Xbox scaler is to offer scaling to whatever your display is set to with zero additional cost to the game engine.
