Robert Downey Jr. has some harsh words for British Channel 4 News interviewer Krishnan Guru-Murthy!

After walking out of an interview with the journalist last week -- prompted by an uncomfortable line of questioning about the 50-year-old actor's past -- Robert went on Howard Stern, where he vented about the painful interview.

The Marvel's Avengers: Age Of Ultron star calls Krishnan a "bottom-feeding muckraker," and says he only wished he would have "left sooner."

"What I have to do in the future is give myself permission to say, 'That is more than likely a syphilitic parasite, and I need to distance myself from this clown.’" said Robert. "Otherwise, I’m probably going to put hands on somebody, and then there’s a real story."

Robert goes on to reference Krishnan's previous run-in with Quentin Tarantino during a press interview he did for Django Unchained, where he questioned the director's use of excessive violence in his films.

"I know that he pulled the same garbage on Tarantino," said Robert. "And Tarantino stayed in his chair and lit him up for five minutes."

Krishnan gave his account of the snafu to the Guardian.

"I want something serious and illuminating, they just want publicity," said Krishnan. "Maybe we and the movie stars should just go our separate ways, and find people more suited to our needs. But I think that would be a shame."

Yep. Still hard to watch.

Now let's kick it back to 1987 where an incredibly bashful Robert Downey Jr. trying to get used to seeing himself on the big screen.
