Re: 'X-men: DOFP' Official CAST Thread (announcements and discussion)
I, for one, find this good news. The movie's turning out exactly how I have been imagining it. This doesn't create a continuity problem, it actually fixes it. Havok and Banshee would just be considered a temporary team that helped Xavier out for that mission. It is unfortunate that their characters weren't developed in FC, but that doesn't mean they need to be developed in DOFP. In franchise history, they'll just go down as minor supporting characters and honestly it was fortunate to even see those B-comic characters with speaking roles.
It was never concretely spelled out that Xavier formed the X-Men right away. After his injury, he might have taken time off or just opened the school for "basic" mutant education. Now, if DOFP (or the next X-movie) introduces a young Scott and Jean, then this would actually be a continuity FIX for how Scott and Jean (and maybe eventually Storm) were his first X-Men students.
I'm still holding out hope for Emma. Yes, Jones wasn't that great, but I'm sure she can do better. Emma is definitely an A-list character.
