Re: ***Official X4 Campaign*** [JOIN US!]
DOFP isn't a true X4 if the cast of the original trilogy is sharing the film with the cast of First Class. Unless the cast of the original trilogy gets 70% of the airtime then this movie could be considered as X4. DOFP is a cross-over film just like The Avengers. And they could still do a X4 movie even if only 25% of the cast from the OXT returned and 75% of the cast is new.
