Marvel: A walking tree and talking racoon? No sweat.
Marvel: A guy who shrinks to super-small sizes and communicates with ants? Done.
FOX: The "First Family" of comic books with over 60 years of history to pull from with characters that can burst into flames, blast force fields, survive a fight with the Hulk, or has a genius mind, and a villain who can AND HAS taken over the world on multiple occasions? ...a failed movie and sequel AND reboot, all within a decade.
@Hurvl: The foriegn box office (even though it's only a about $35 million rightn now, which is horribly low for an action flick) will probably be the movie's only saving grace. And even then, FF may only just barely break even on its budget.
Addendum: It will do better overseas because of the less-critical viewers/ fewer comci book fans. Also, foreign movies are seldom made with big-budget effects, so even an American one with minimal SFX will do well.
