Despite the fact that he directed X-Men: First Class and has written the treatment for its sequel, Days of Future Past, Matthew Vaughn has decided he's not going to take the top job. In an odd bit of shuffling, 20th Century Fox is eyeing Bryan Singer as his replacement. Singer wrote the treatment for the 2011 prequel and, of course, did a great job directing the first two X-Men movies. Nothing is final yet. While we're shuffling things, can we get Kelsey Grammer back as Beast? Because that would be fun.
