First one that someone briefly mentioned, Toy Story 3. Really fun game, especially the Toy Box mode. I had a blast with that game - I didn't plat it just to get an easy plat, I did it because I couldn't put the game down. I need to get this one back in my collection.
Now for one that hasn't been mentioned yet, The Adventures of Tintin is surprisingly good. It's a platformer along the lines of classic Prince of Persia or Out of this World, lots of puzzles, characters with different abilities, etc. Highly, highly recommended game - it's far better than it has any right to be.
