Following having left Marvel Comics, Brian Bendis is now over at DC Comics, and it's also learned Fox Studios has picked up Bendis to write a new Kitty Pryde X-Men movie, which will be directed by Deadpool's Tim Miller.
I'm no fan of Bendis, so this remains to be seen if it will be any good (and the reason¬†Bendis¬†only sold a lot of comics, IMO, is because he has always been paired with A-list artists and received heavy promotion that a lot of writers at Marvel never received).
We can also guess that when Fox Studios moves over to Marvel Studios, Bendis won't be around, so at least Bendis on X-Men will probably be short-lived, thankfully.
It's reported the X-Men spinoff movie is presently being developed under the code name "143" and will be set within the X-Men universe¬†focusing on Kitty Pryde, a mutant who can phase through objects.
"143" is a reference to Uncanny X-Men #143 featuring¬†Kitty Pryde¬†versus a demon in the X-Mansion.
Kitty Pryde was most recently played by Ellen Page in 2006's¬†X-Men: The Last Stand¬†and 2014's¬†X-Men: Days of Future Past.
