The movie Avatar is the second highest-grossing movie of all time, beaten only by Avengers: Endgame, and it came out more than a decade ago. Now knowing the success of the movie, it is very surprising to think that an actor could have rejected an offer to star in it.

But that's exactly what Matt Damon did. Not only that, the movie director James Cameron possibly offered Matt Damon 10% of the film's profits. The actor didn't explicitly say that the 10% was from the profit of the film, but we could assume that from his regret over not taking the role. It is understandable, because Matt Damon would have earned more than a quarter of a billion!

He explained that he denied the role because he thought that would have caused a problem for Paul Greengrass and his friends on The Bourne Ultimatum. The actor didn't go into further detail, just said that he couldn't do it.
