Why isn't the sequel in the works already?

Rating: 8/10 (3 May 2008)

I love Marvel over DC, but I didn't know anything about Iron Man. So, I read the article on Wikipedia and was glad to do so. Jon Favreau just caters to comic book readers and at the end there's a huge twist.
If you don't go in without knowing about the story, it will still be a really good movie, but you will miss a few very well placed jokes about a sequel and who will be in it. Robert Downey, Jr. is perfect for the lead role and the supporting cast was great as well. The effects like the other person said, were not overdone and very believable. It made for a more flawless movie. I was also glad not to see any stupid montages. Most of the time that is just a way to cut corners like in Fantastic four. If you are going to do the origination story, give it as much substance as possible.
This is the second best Marvel movie I've seen. Spider-man 2 still reigns supreme.
Note: Stay after the credits, there's a little something at the end.
