Quoted from the Philadelphia Style :
In X-Men: First Class, slated to open in early June, Bacon plays mutant villain Sebastian Shaw. Although it’s his first major action role (the only thing that comes close, he says, is 2000’s Hollow Man), it’s not a particularly demanding part physically. “I’ll let the younger actors do that,” he laughs. “I’m more one of those sit-in-my-chair-and-destroy-the-world type of guys.”
Kevin Bacon is Sebastian Shaw.
I really don't have more to say than that. It just seems so very odd.
