Matt Damon offered to play the accountant who flubbed the Oscars Best Picture announcement in a movie if he did "something incredible".
Matt Damon
The 'Suburbicon' actor - who has a long-running fictional feud with Academy Awards host Jimmy Kimmel - was amazed to see how much he looks like PricewaterhouseCoopers partner Brian Cullinan, and ahead of the businessman handing over the wrong envelope to Warren Beatty and Faye Dunaway, who mistakenly declared 'La La Land' the Best Picture winner instead of 'Moonlight', he'd joked that he'd be the perfect choice for a biopic if anything significant happened at the ceremony.
Matt admitted: "I met that guy and commented on it, [saying] 'We look very similar.'
"I said, 'If you do something incredible, maybe I'll play you in a movie.' But I didn't mean that."
And the 'Downsizing' actor insisted he wouldn't have even thought of doing anything to sabotage Jimmy's big night because the talk show host is already capable of messing things up for himself.
He quipped to Yahoo!: "Nobody needs to sabotage that guy -- he does it all to himself.
"I was very outspoken, and I did announce that he was going to blow it and ruin the show somehow. And he did."
During the ceremony, Jimmy took a number of jibes at his pal's expense.
In his opening monologue, he said: "Tonight, in spirit of healing and bringing people together, I would like to bury the hatchet with someone I've had issues with. I would. Matt Damon.
"I've known Matt for a long time now. I've known Matt so long, when I first met Matt, I was the fat one, OK? It's true. And we've had problems. He's a selfish person.
"Those of you who have worked with him know this. But Matt did something very unselfish and I want to commend him for it."
He then explained how Matt "allowed" Casey Affleck to star in 'Manchester by the Sea' - a role which later in the evening won him the Best Actor award - while he took on a part in 'The Great Wall' instead.
He mocked: "He handed an Oscar-calibre role over to his friend and made a Chinese pony tail movie instead.
"And that movie went on to lose $80 million. Smooth move, dumb ass. See? It's so easy to reach out and heal."
Later in the show, Jimmy brought out a bus of tourist and introduced them to some of the biggest stars in the room - and while introducing one to Casey, advised him to "ignore the jerk" behind, who turned out to be Matt.
And the jibes didn't stop there, as the presenter looked back at his foe's role in 'We Bought a Zoo' and observed: "He has almost no discernible talent. But he works."
The 'Manchester by the Sea' producer didn't even get chance to get his revenge as when he and their mutual pal Ben Affleck took to the stage to present an award, music began playing, putting Matt off every time he tried to speak.
Jimmy joked: "Wrap it up! We want to go home!"
