Guess Who Kevin Bacon May Play Now in X-Men: First Class

A few days ago, it was reported that Kevin Bacon had signed on to play a villain in the upcoming movie X-Men: First Class.

However, Fox had declined to say which villain the actor would be playing and preferred to keep mum about it - no doubt to make an announcement at Comic-Con perhaps?

And most people, including me, were thinking that Bacon would be playing one of the X-Men's most nefarious villains, Mister Sinister.

Now, a story over at Forces of Geek (based on a source they have) is claiming that Bacon will play Sebastien Shaw - another nefarious villain - who is the leader of the Hellfire Club:

A mutant, Shaw possesses the ability to absorb kinetic energy and transform it into raw strength. He is the leader of the New York branch of the Hellfire Club, an exclusive secret society bent on world domination, although to the public, he is a legitimate businessman and ordinary human. He once funded the mutant-hunting Sentinel program to keep it under his thumb. In 2009, Shaw was named IGN's 55th Greatest Comic Book Villain of All Time. [Wikipedia]

 It seems that Sebastian Shaw figures heavily in the film's plot.

Keep in mind that nothing has been confirmed yet and list this news under rumour, though it's a very plausible one.

What say you - Sebastian Shaw or Mister Sinister for Kevin Bacon?
