Oh crap! That image makes my worst nightmares about this movie became true!!! No big-time heroes... (except for the Beast at the back of the pic) no famoes actors, a crappy story that isnt neither a prequel to the prior films, or true to the comics... I suppose the best I can expect are cool minimates from Art Asylum!
By the way, any guesses on who is the black-haired chick at the right? From what I can guess we have(from left to right):
young Magneto, Moira, Emma (veeeery hot), Nightcrawler´s father (that demon mutant whatever he is called), Beast, Havok, "black-haired chick", Mystique and young Xavier.
