Promotional tours are usually fairly easy stuff. Celebs go on a ton of different television shows, answer the exact same questions on every one, and try their best to promote their new movie. It’s tedious, but it’s certainly not hard work.

Robert Downey, Jr. is a veteran of these things. He’s been acting for years and the resurgence of Marvel super hero films has his career at never before seen heights. Between the Iron Man franchise and his role in the The Avengers series, Downy could probably get through one of these things with his eyes closed. However, in this case he simply walked off the set.

When Channel 4 News interviewer Krishnan Guru-Murthy asked Downey about his past bad habits, which include multiple arrests and rehabs for alcohol, cocaine, heroin, and marijuana. He also had a difficult relationship to his father, which was brought up. Downey instantly called it a day, walking off the set leaving Guru-Murthy struggling to apologize and try to keep the interview going. Dude, don’t insult Tony Stark.

Skip to about the 6:00 mark of the video to watch Downey peace out.
