Maybe you've heard of it. Maybe.
Anyway, the cast was amazing. Particularly these two gentlemen:
James McAvoy (Professor X) and Michael Fassbender (Magneto)
What I really enjoyed about their performances was that, in the back of my mind, I kept remembering Patrick Stewart and Ian McKellen, the actors who play these characters "in the future". And all the while, I kept telling myself, "I can totally see these two growing up to become those other two."
In other words, their backstories were great, but the way they interpreted how those backstories make them the men they will become was flawless.
So I got to thinking: how do you do it? Does a character's backstory come first, or is the character's future much clearer to you during the brainstorming process?
Also, go see X-MEN First Class. Even if you hate superhero movies. It's just that good. :)
