From Showbiz 411:
I told you some time ago — exclusively–that Michael Fassbender, hot as a pistol, had to choose between roles in the new “X Men” and “Spider Man.” I am told he has made his choice, and will appear in “X Men: First Class.” James McAvoy and Benjamin Walker are also cast in Matthew Vaughn’s upcoming blockbuster. All this news makes me want to see this movie before it’s even made!…It's getting to the point where so many actors have been cast in two or more comic-to-film adaptations. This will be Fassbender third comic book film, he was in 300 and Jonah Hex. James McAvoy was in Wanted.
