Did you get the movie reference?
Once again, Jon Favreau is money. So money. But I think he knows it this time:
... if everybody comes out to see the movie and it's successful, then I'm sure Marvel's going to want to do another one and if they want to, I've got another two movies in my head and I'm ready to go and I know the cast feels the same way.
Sweet. (Marvel has already announced plans for Iron Man 2 in 2010.)
