Bryan Singer isn't returning to the "X-Men" franchise yet, but one of his more frequent screenwriters is.  Christopher McQuarrie is the Oscar-winning scribe behind "The Usual Suspects" and "Valkyrie."  What many don't know is that he was a key creative force behind Singer's first "X-Men." Now, according to The Hollywood Reporter, McQuarrie is developing the second installment of the "Wolverine" franchise.

Fox, producer and star Hugh Jackman and Lauren Shuler Donner have already decided to base the movie on the classic Chris Claremont/Frank Miller mini-series of the early 80s.  That storyline found Wolverine coming to grips with his animal instincts by studying the martial arts.  Oh, and he fought a lot of ninjas too. This probable direction was hinted at in one of the surprise scenes following the credits of "X-Men Origins: Wolverine."

The first "Wolverine" grossed $180 million in the U.S. and over $363 million worldwide making it one of the biggest hits of the summer.  A spinoff based on "Deadpool," also introduced in "Wolverine," is also in development.

McQuarrie also has a number of other projects in development including "No Man's Land" and "The Tourist."
