Graphics are broken up into two styles. There are the straight-from-the-film cut scenes with voice-overs by the films' actors giving a brief overview of a scene. and then there are the in-game graphics. Of course, the pre-rendered stuff from Fox Animation are the best looking visuals in the game, but that is to be expected. In-game stuff isn't that bad looking. Most characters and environments are detailed and really help pull you into the game. Scrat himself looks just as furry and frustrated as his silver-screen counterpart, while supporting characters like Manny and Sid (well supporting in the game, not the movie) also come off nicely.
Visuals aren't the only aspect coming from the film. Chris Wedge, Ray Romano, Denis Leary and John Leguizamo all reprise their roles for this game. Chris Wedge (the squeaky, grunting voice of Scrat) does his usual top-notch job of conveying meanings without actually using words. Interestingly enough, the number of sound-clips used for Scrat might not be a whole lot, but since what he says isn't intelligible, his in-game "comments" never get annoying like other games where the character actually throws out understandable one-liners all the time.
