Re: Wolverine in X4 or NO? Poll to end the debate
Would it be possible to do an X4 without Logan? Yes. Would it be ideal? No.
I've heard that Hugh's schedule might make it impossible for him to be in the next installment, if the next installment were to come at any reasonable time (as opposed to 5 years down the road). If that's true, then the movie would do just fine without him. If they can get Hugh, though, they should. The movie would be better with him as a supporting character.
So, my answer is: Yes.
