Re: How should they handle Wolverine in this movie? (if he had to be in it..)
The best option is letter A.
-No need to reintroduce Wolverine because we already saw him before unlike if they go with the Wolverine from the First Class timeline.
-He was the face of the original trilogy so it just makes sense if he they gave him the time-traveler role.
-If they are going to feature the "future world or timeline", its best that they include the most popular character in the movie series.
