i dunno... i mean even Matt Damon was turned down for the part of Kirk in the new Star Trek 'cause he was too old for the part, they wanted to portray a younger Kirk of course, and i think that's the problem with a lotta these movies, they're casting older actors with younger actresses, now i admit i love Robert Downey, Jr., as Tony Stark, he's funny and all that, he's perfect for it, Samuel L. Jackson i heard has just been cast for NINE films as Nick Fury, and the guy's already like late 40s, early 50s, i think they should just start fresh with up-and-coming actors who can actually act and play the parts, maybe follow the storyline of the Ultimate universe, but make it more realistic like The Dark Knight, nothing so cliche
