Jeremy Irons is good casting! I didn't even register Brad Pitt for some reason and Goldblum was my original choice for Reed, but I changed it due to his height and being a little older than I wanted.Jeff Goldblum - Reed Richards
Robin Wright - Sue Storm
Ron Perlman - Ben Grimm
Brad Pitt - Johnny Storm
Jeremy Irons - Doctor Doom
Rickman would be my pick for Doctor Strange.
I can see that.Great FF casting, but Rickman is a bit of a generic choice for a villain, and he would't play it straight anyway.
Kyle MacLachlan - Mr Fantastic
Laura Dern - The Invisible Woman
Dana Ashbrook - The Human Torch
Jack Nance - The Thing
Dennis Hopper - Doctor Doom
Harry Dean Stanton - Mole Man
David Bowie - Namor
Crispin Glover - Silver Surfer
Frank Silva - Galactus
