Entertainment Movies Historical Movies James Cameron Says Matt Damon Should Not Regret Turning Down Lead 'Avatar' Role: 'Get Over It' "We have to do it so the world is in equilibrium again," James Cameron said of having Matt Damon cameo in a future Avatar sequel By Tommy McArdle Tommy McArdle Tommy McArdle is an editorial assistant on the Movies team at PEOPLE.

In a recent interview with BBC Radio, the Avatar series filmmaker laughed when he was asked how recently he had spoken with Damon, who famously revealed in 2019 that he reportedly lost out on a $250 million payday by turning down the lead role — and 10 percent of the film's profits — in Cameron's original 2009 film. "He's beating himself up over this," Cameron, 68, joked to the outlet over the money Damon, 52, claims he lost out on. "And I really think you know, 'Matt you're kind of like one of the biggest movie stars in the world, get over it.' " "But he had to do another Bourne film which was on his runway and there was nothing we could do about that," the director said of the missed casting opportunity. "So he had to regretfully decline." Asked whether Damon could appear in a cameo in a future Avatar movie, Cameron appeared interested.

"But he doesn't get 10%, f--- that." Damon had previously said in a 2019 interview with British GQ that when Cameron offered him the lead role in Avatar as Jake Sully, the director promised that if Damon did not take it, he would cast an unknown actor.

I don't need a name for this, a named actor. If you don't take this, I'm going to find an unknown actor and give it to him, because the movie doesn't really need you. But if you take the part, I'll give you ten per cent.'" "I told John Krasinski this story when we were writing Promised Land." Damon added, revealing his friend's reaction to the news. "He goes, 'What?' And he stands up and he starts pacing in the kitchen. He goes, 'OK. OK. OK. OK. OK… 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.'"

I've left more money on the table than any actor actually," he said. Damon said at the time that his real regret from turning down Avatar — the role eventually went to series star Sam Worthington — stems from potentially missing out on his one chance to work with Cameron.

I didn't realize that," the actor explained at the time.

"So it feels like he's made more than he has. 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," he said, jokingly adding: "My kids are all eating. I'm doing OK." Avatar: The Way of Water is now playing in theaters.
