During the premiere of his movie The Great Wall, Matt Damon revealed some news about another role he’s taking on — a cameo in the female-led Oceans Eight (joining Vogue’s Anna Wintour).

“I haven’t shot anything at this point,” he said to Extra. “But I think I’m gonna do a little cameo.” When asked what he and his lady did for Valentine’s Day, he replied, “It was good. It was nice. She still talks to me, which is great… It turns out that’s an important part.”

He also joked about his comedic/rivalry with Jimmy Kimmel, who will be hosting the Oscars this year: “I’m gonna have to see him again at the Oscars, which is a real bummer ’cause that’s live and he’ll probably say something horrible about me,” he said, “but I come to expect that from him.”
