I was waiting to see if RDJ could pull off being Tony Stark and he did in spades. He made Stark come to life in a great performance. Gwyneth Paltrow played Pepper Potts to a tee. I so did like the take out the trash line. My only complaint was the soft voice used by Terrence Howard as Rodney's voice should have been more manly.
If you have to see one movie this year, Iron Man is the one.
Great action, lots of humor, and a great plot. Overall the movie was in line with the comic book, although they did update it a bit and included Obie Stane.
