|Uma Thurman and Robert Pattinson in 'Bel Ami'|
He told Scottish newspaper The Herald: "There are lots of attractive women in the film. Christina Ricci, Uma Thurman and Kristen Scott Thomas ... And I sleep with all of them!
"The thing that stands out in the story in 'Bel Ami' is just his behavior - the women that he manages to screw over are all attracted to him to begin with and so he starts having affairs with them and destroys their lives afterwards. That's kind of nuts."

Robert also revealed it was fun to play a character who is the exact opposite of vampire Edward Cullen, who has an old fashioned view of romance, from the 'Twilight Saga'.
He explained: "My 'Bel Ami' guy doesn't have a conscience. Most fictional characters are driven by some target, but he is like a reverse character. He's so content to do nothing and thinks everything should just be given to him. But if someone slights him, or directs any insult at him, the most overwhelming energy grabs him and he turns into this absolute devil who will do anything.
'With 'Bel Ami', I guess there is something quite fun about going from Edward Cullen to playing a guy who pretty much abuses women to get money out of them.
"Edward so wouldn't approve! So, yes, I thought that was a funny irony. But the story, independently, is great, and I only thought about the irony afterwards.
"Doing something like 'Twilight' opens doors and it closes others. You can say, 'Oh if I was still unknown, then no-one would judge me,' but at the same time, nobody would give a s**t either. It's a weird little balance. And, most of the time, you are just completely guessing what people do, so I suppose doing scripts that you think are good is the way to go. And that's what I thought about 'Bel Ami'."
