Like I said, it's possible Bryan was in charge of everyone else. But McAvoy and Fassbender were strictly Vaughn. He picked McAvoy first and then auditioned a bunch of Magnetos with him. In an interview I read, the second after he saw the screentest with Fassbender, he ran to one of the co-script writers, played the tape, and said, "JUST LOOK AT THEM".
The other actors beyond Charles' and Erik's aren't really standout, but I do know Vaughn was behind Flemming as Azazel. The actor is is "lucky charm". I'd be curious to know who picked Lawrence.
