The Academy Award-winning star, 48, revealed that he turned down the lead role of Jake Sully in James Cameron's 2009 megahit film "Avatar" and regrets not being able to work with the groundbreaking director.
Not only did he pass up a unique work experience, but he also gave up a potentially massive payday -- something in the nine-figure range.
“Jim Cameron offered me 'Avatar,'" Damon told British GQ.
"And when he offered it to me, he goes: ‘Now, listen. I don’t need anybody. I don’t need a name for this, a named actor. If you don’t take this, I’m gonna find an unknown actor and give it to him, because the movie doesn’t really need you," he continued. "But if you take the part, I’ll give you 10 percent" of the film's profits.
"I told John Krasinski this story when we were writing 'Promised Land.'… He goes: ‘If you had done that movie, nothing in your life would be different. Nothing in your life would be different at all. Except that, right now, we would be having this conversation in space,'" Damon explained. "So, yeah. I’ve left more money on the table than any actor actually."
GQ did the math. Damon would have been a quarter of a billion dollars richer, since "Avatar" went on make $2.79 billion at the box office. It was the top-grossing movie of all time until "Avengers: Endgame" dethroned it this summer.
Damon recalled that shooting "Avatar" would have conflicted with his "Bourne" series, and he "couldn't do it."
“Cameron said to me in the course of that conversation, ‘Well, you know, I’ve only made six movies.’ I didn’t realize that. He works so infrequently, but his movies, you know all of them. So it feels like he’s made more than he has," Damon said.
"I realized in having to say no that I was probably passing on the chance to ever work with him. So that sucked and that’s still brutal. But my kids are all eating. I’m doing OK," he joked.
The role ultimately went to Australian actor Sam Worthington, a relative unknown at the time.
