Guy Pearce is a memorable supervillain, I hope that wasn't a spoiler, but its obvious he wasn't going to be playing Stark's best buddy.
Highly recommended. 4 out of 5.
Alrighty, then, I might go to see Iron Man Three just for Guy Pearce. While I liked the first 2, I don't know why I have no strong desire to see this one. I actually think the big summer movie that interests me most is World War Z, as I read and enjoyed the book. The scene in the trailer where the zombies are all climbing on top of each other is freaky.
