If you saw Pixar's Up tonight, you probably saw the teaser-trailer for Pixar's upcoming Toy Story 3. And it's very likely you were happy about it.
If you didn't, you can see it at the Apple trailer page (or at the official Disney site, but you'll have to put up with a commercial first; I'd stick with the Apple site).
Looks like they managed to fit everyone into the teaser and all the original voices are back (except for the late Jim Varney's Slinky Dog, presumably), and they even crammed in some new toys. So far Pixar has never let me down — Cars was the weakest for me, mostly because they stuck race cars into Doc Hollywood, and even that was fun to watch — so I'm officially already looking forward to this.
And if you haven't seen Up… go see Up.
