curious what avatar would be like with him.

i wonder how different the movie would feel with damon as lead.

That's a crazy $250M what-if; imagine the box office swing. #mattdamon

damon is still great, but this shows how big a choice cameron made.

interesting story, not sure a different actor would have changed the outcome much. #mattdamon

This just proves casting can shake up a film's fate.

love this kind of film history speculation.
