I'm glad Downey fought for this role, he was absolutely perfect for it. I seriously can't see anyone else performing the role of Tony Stark with the wit, humor, and intelligence he gave to this role. Lots of fun, great special effects, seamless CGI, plenty of action ... and I've already gone to see it twice. You're gonna love it!
I thoroughly enjoyed it and it was great watching Jet Li and Jackie Chan together. I thought the initial fight scene between the two was terrific, bringing together all different kinds of fighting styles. It's awesome watching these guys doing their fight scenes, moving so fast, the camera had a hard time keeping up with them, with just enough slomo to accentuate, but not irritate. Great fun and definitely a keeper.
