Now that he's officially signed to develop and direct the film, Bryan Singer has begun to talk - at least, to drop hints - about mutant prequel pic X-Men: First Class.

Chatting with the Hollywood Reporter's Heat Vision Blog, Singer admitted that while he couldn't talk specifically about the story (it's still a secret), he could lock down what part of the X-story it would cover. "It’s basically about the formation of the X-Men. How they began and the relationship between a young Xavier and a young Magneto."

And since it'll borrow elements from Eric Lensherr's longer life, it's even more likely that the Magneto origin movie will be shoved back on the schedule as Fox concentrates on this. "This story would probably utilize some of the Magneto story because it deals with a young Magneto, so it might supersede that because this would explore that relationship between a young energetic professor and a disenfranchised victim of the Holocaust."

But even First Class will have to wait in line behind Singer's planned fantasy pic Jack The Giant Killer, which is his next scheduled movie. "Right now that is the plan. Unless there's a problem in the development process. There is a script for "Jack"; we're in visual development. We've got artwork and pre-viz that we are doing. But you never know how things go."

He talks more about Battlestar Galactica and Excalibur, both of which sound like they're still far from certain just yet, so go take a look.
