They'll have to find a new actor. Fox maybe nervous with using Tyler kitsch( his Gambit was decent comparing the casting of others by FOX) as a leading man, given his recent box-office bombs. I would rather see Gambit as apart of a X-Men movie being a X-Man, versus a solo film of him, we have GAMBIT vol.5.
In fact, I really want to see Gambit more active as a X-Man in general. He hasn't appeared in Uncanny for 10 years, really. That's pretty F'd up if you ask me. There needs to be another book that features Gambit as a X-Man other than Astonishing.I was sad to see X-Men vol.3 end just as Storm was leading.
The Gambit/ Storm dynamic would be a great way to reintroduce Gambit into a active X-Men team. Besides Rogue/Gambit, Storm/Gambit stories are probably the most fun you can have. and you don't really need to worry about romance b.s.
(Even though it would make alot more sense than other couples Marvel throws together these days)
