my favourite bit in x men 1 is actually through 3 deleted scenes, its some brillaint character development for jean cyclops and storm, something which they lacked.
the first one is xavier and jean in cerebro, talking about how with charles jean wouldnt have had much of a life, its nice how she calls him charles as well, shows the relationship
the next one is storm talking to rogue, its the first time we hear storm actually in a conversation, we dont see her properly talk to anyone until her chasing wolverine as he is about to leave, anyway, she asks rogue how she is, her accent is brilliant and she comes across as the mother of the school, whih is brillaint
the next scene is the extended bedroom scene, jean explains why cyclops is so controlled and then cyclops and logan have an extended argument, scotts beliefs are shown as he states he is a proud mutant, love this scene as he kicks logans ass, as he should do after logan stealing his role in x3
