According to IESB.net, Brendan Fraser confirmed at the New York Comic Con that he will be involved with the G.I. Joe movie scheduled for 2009. See the video here

This cast is getting crazier and crazier as the days go by. I'm still a little lost as to thoughts on how this might turn out. I wasn't a HUGE G.I. Joe fan (more of a He-Man, Ninja Turtles, Transformers guy), but I had my share of Joe's and I was somewhat familiar with the cartoon's plotline. As far as I can tell this movie is adding up to be a disaster, but we'll just have to wait and see.
