IMDB has Famke Janssen listed as "Jean Grey/Phoenix", so it looks as though they are at least beginning the Phoenix saga. However, since the movies vs. comic book timelines/plotline has been completely different, it remains to be seen what role Phonix will play. I'm kind of sad that Alan Cummings won't be reprising his role as Nightcrawler. And Kelsey Grammer as Beast?? Should prove to be interesting (although it may be difficult to not keep seeing Beast as Sideshow Bob
) .
