Re: Expanding the Marvel Cinematic Universe with Sony and Fox
Until they reboot the X-men I don't see Marvel wanting stuff like X3 or XOW attached to their MCU in any way. Spidey just rebooted so that could work. However FF while being rebooted is now going to be compromised by getting attached to the existing X-Men mess. Had XMFC been a true reboot then all this would have been possible but Singer has a death grip on that franchise over there at Fox. He won't let go nearly as easily as Raimi did.
There's no such thing as a movie that's too big to fail.
