Robert Downey Jr. seemed to be channeling Tony Stark’s intensity in an interview with the U.K.’s Channel 4 News, walking out of the room when asked about his past.

Journalist Krishnan Guru-Murthy tweeted the video of his “Avengers: Age of Ultron” promotional interview with Downey Jr., captioning it, “A steely moment from Ironman.” In the video, Downey Jr. appears rather irritable from the start, but the interview really starts to go south when Guru-Murthy asks him to explain the following quote from a 2008 article in the New York Times: “You can’t go from a $2,000-a-night suite at La Mirage to a penitentiary and really understand it and come out a liberal,” Downey Jr. said.

When pressed on the subject of his past, the actor says, “Uh, are we promoting a movie?” As the interviewer attempts to justify his questions, Downey Jr. says, “I’m sorry, I, I really don’t — what are we doing? Bye.”

As he leaves the room, he says, “I’m sorry, it’s just getting a little Diane Sawyer in here.”
