In an interview with ComingSoon.net, Marsden revealed that he'd love to play Cyclops once again when asked about returning for X-Men: First Class but it seems like he hasn't heard anything quite yet:
"I would not think twice about being part of any incarnation of the "X-Men" films. Another one I know nothing about but we got to be very close on those movies. It was a family and a formula that really worked. That would really excite me and please me to go back to that."
"You just have to cross your fingers and hope that it comes together. You want nothing more as an actor to be doing work that people love and the couple of "X-Men" movies that I was lucky to be a part of were examples of films that worked on so many different levels. It's so rare to be a part of something like that."
The movie currently has no release date but is being produced by Bryan Singer and Lauren Shuler Donner. No director or cast members have been announced yet.
