It's surprising that anybody could have thought Sam Jackson's appearance in 'Iron Man' was a..."cameo"?... Please. Makes no sense. This from the write up that's been in the Canadian press:
The actor confirms he's already received word the eye-patch-wearing operative will have a more significant role in the sequel, due in May 2010. "I saw (director) Jon Favreau last night. He walked up and said, 'Hey, I hope you're making your deal.' "
Of course. Duh.
