Yes! For some reason every time I saw him in the cartoon I always pictured James Earl Jones. The choice for Rogue was bad, but I was initially disappointed with the casting choice for Magneto too. Ian McKlellen (sp?) is a good actor, but I definitely was not expecting a wrinkled old man to play the part.
The best casting choice they made by far was professor X. I guess someone else will be playing him in the next movie. And why are there no sentinels? Was that just part of the cartoon? I thought they were supposed to be around too. That would definitely step things up.
They weren't ready for Apocolypse and they bet not try to bring him in if there is an X4.
120 million in one weekend was based on the hope that they would stick with the comic. Now that we can see they haven't, expect a lower turnout if there is an X4. If you didn't know anything about the comic strip then it was a good movie, but a good portion of that 120 mil was straight comic book fans.
Also, as far as Magneto, I think they did a good job casting ol' dude to play the part b/c you have to consider that Magneto is a survivor of the Jewish concentration camps...in World War 2...so even by comic book law, he must be at least 50 years old.
