I can't get enough of Iron Man previews — this older one was awesome, and so is this one below. Maybe it's the smoldering Robert Downey Jr. or the high-tech action sequences? Or maybe I'm projecting my excitement for the video game — but whatever, I know I'm seeing this on opening night (May 2nd!). The best, geekiest line from these trailers so far? "I don't want to see this on your MySpace page!"
