When the film was over, I watched some of the special features. I began with the animated short "Boog and Elliot's Midnight Bun Run," a fun little four minute short subject.
Next, there was a ten minute short on the voice cast for the film made up of some well-known names in the business: Martin Lawrence, Debra Messing, Ashton Kutcher. Billy Connelly, Gary Sinese (who was the best thing in the film).
And then there was a 15 minute "making of" featurette which explains the layering process in which one of these CGI animations gets made. OK information and a nice start to Sony's animation division.
