Robert Downey Jr. walks out of "Avengers" interview over personal questions

Robert Downey Jr. cut an interview promoting the new "Avengers" film short after the questions got increasingly personal.

The actor sat down with Krishnan Guru-Murphy of Britain's Channel 4 News to discuss "Avengers: Age of Ultron," but about halfway through the interview he began asking about Downey's past -- including his drug addiction and time in jail, as well as his political views.

Downey can be seen getting increasingly uncomfortable as the interview progresses ("Are we promoting a movie?" he asks at one point) before finally shutting the whole thing down.
