Ricky Gervais says Johnny Depp was "outrageous" and broke a window when they worked together.
The Hollywood star features in an episode of Ricky's new television show Life's Too Short.
Johnny plays an exaggerated version of himself, seeking his revenge on Ricky for ridiculing him at the Golden Globe Awards earlier this year.
Ricky was thrilled to collaborate with Johnny, revealing the hunk revelled in his role.
"Johnny Depp is amazing, he is incredible in it," Ricky told UK TV show This Morning. "People say he is shy, but he's not shy, he is outrageous. He broke a window in one scene throwing fruit at me. The first banana I caught, but the apple it just missed me and it broke a window. And then we all laughed."
During his scenes, Johnny berates the British comic for publicly mocking his movie The Tourist. Ricky claims that Johnny was so convincing, some viewers actually believed he wasn't acting.
"We put that clip out and some people thought it was real. They thought that Johnny Depp would come to my office and have a go at me while we filmed it with three cameras - and then it leaked on the internet," he laughed.
"He is playing a Johnny Depp who is doing the film Rumpelstiltskin and he is playing a dwarf. So he hires Warwick to get into the headspace of a dwarf. Of course, he makes Warwick do stuff and it's hilarious.
"At one point Johnny was ad-libbing and he said to Warwick, I'm going to kiss you now,' and Warwick looked over at me and I said, Look if Johnny Depp wants to kiss you then'"
Life's Too Short stars Warwick Davis and is written by Ricky and Stephen Merchant.
Ricky and Steven previously worked on UK TV show Extras, which featured appearances from stars including Kate Winslet, Robert De Niro, Daniel Radcliffe and Chris Martin.
Ricky has revealed many famous faces approached him about appearing in Extras and they were always willing to make fun of themselves. He is planning to sign up some celebrities for his latest project.
"With Extras there were a lot of A-list stars involved, people would come up to me and say, Oh, I wanted to be in that.' So now we are soaking them up for this," he explained. "It is so much fun and I had a little taste of my own medicine because I have just done Curb Your Enthusiasm, playing myself. And the further you go, and the more outrageous you make yourself, the more fun it is. So I can see why they do it now, because they are saying, This can't be me.'
"I don't think we have ever had a person say, I'm sorry I can't do that.' The opposite is often true."
