Timothee Chalamet got a stern warning from a background actor on Marty Supreme.

The 30-year-old actor tried to frustrate the unnamed extra for a shock incident scene, in which Timothee's character, Marty Mauser, plunged through the floor of his motel room while taking a bath and landed on a gangster's arm and his dog.

And after some takes, the background actor told Timothee that provoking real anger was dangerous because he had spent "30 years" in jail.

During a Q+A session with 60-year-old actor Robert Downey Jr, held at the DGA Theater in Los Angeles on Wednesday (14.01.26), Timothee recalled: "I won't say who, but in that motel sequence, there are a lot of non-actors … that I find it really thrilling to work with, but sometimes it would take multiple takes to really get something out of them.

"And I'm really getting in the guy's face, and I'm really trying to get him angry with me. I was saying to Josh [Safdie, the movie's director], he's not getting angry with me, he's not getting angry with me.

"I did another take, and then the guy said, 'I was just in jail for 30 years. You really don't want to f*** with me. You don't want to see me angry.'"

With a nervous laugh, Timothee added: "I said to Josh, Holy s***, who do you have me opposite, man?"

Marty Supreme is loosely based on the real-life table tennis great Marty Reisman's journey to becoming a champion in table tennis.

And Timothee picked up his first Golden Globe Award on January 11, after being triumphant in the Best Male Actor in a Musical or Comedy category, thanks to his work on the 1950s-set ping pong drama.

The star - who beat Leonardo DiCaprio (One Battle After Another), George Clooney, (Jay Kelly), Ethan Hawke, (Blue Moon), Lee Byung-hun (No Other Choice) and Jesse Plemons (Bugonia) in the "stacked" category - said: "This category is stacked. I look up to all of you."

Timothee thanked the cast, his parents and 28-year-old partner, socialite Kylie Jenner, as well as Josh, 41, whom he expressed his gratitude to "for this role".

He added: "Thank you for believing in me, thank you for this portrait, for your mind, for your worldview."

Timothee then gave a shout-out to his 71-year-old co-star Kevin O'Leary (Milton Rockwell).

He quipped: "If you would have told me when I was 19 years old that I'd be thanking Mr. Wonderful from Shark Tank - all right, you're laughing, so I got away with that, thank you, Kevin.

"I would have been stunned, but I'm very grateful."
