EXCLUSIVE: Billy Bob Thornton Almost Joined The ‘Iron Man’ Cast…As Tony Stark!

FROM SPLASH PAGE: When it comes to casting movies based on the comics world, it’s always interesting to play the “What If?” game when we hear about actors who were almost chosen to play certain roles.

What if Sam Rockwell had landed the Tony Stark gig in the first “Iron Man” (instead of playing the villainous Justin Hammer in “Iron Man 2″)? What if Mark Ruffalo was offered the part of Harvey Dent in “The Dark Knight“?

Now you can add this one to the list of almost-casting points to ponder, folks: What if Billy Bob Thornton played Tony Stark?
