Pattinson and Ricci both completed "Bel Ami" which Pattinson plays a young man rising to power in Paris using the city's most influential and wealthy women.
"The world is used to seeing him one way, and he's very, very different in this movie," Ricci tells PopcornBiz from the Blackberry Torch from AT&T launch party, "But he's an actor, that's what it's about. And he's really great in this."
Pattinson, who somehow has managed to stay a faithful and sexless through three "Twilight" films, works his way through Parisian society in "Bel Ami." At the press conference during the "Eclipse" release, Pattinson gleefully talked about his "Bel Ami" character Georges Duroy who he called "a completely amoral, evil character."
"He seduces his wife and seduces absolutely every single one of his wife’s friends. Any influential woman he can get he has an affair with," said Pattison. "And then ends up screwing over the entire society and ends up making millions and millions of francs."
Pattinson taps into some serious actresses in Ricci and Uma Thurman. His Duroy is such a cad that he not only dumps Ricci once, but several times as he rises to the top.
"We have an on-off relationship through the whole movie and I get my heart broken a few times," says Ricci.
And does she handle her onscreen heartbreaks with less drama than Pattinson's co-star Kristen Stewart who famously went through vampire withdrawal during "New Moon" in a big way?
"Yes, I do," she admits. "But there's a little screaming, but that's par for the course for a relationship."
While filming is complete, no official release date has not been set for "Bel Ami," -- though it looks to hit US screens in the spring of next year.
Folks who prefer the nice Rob won't have to wait long. Pattinson will be back to his filming his faithful vampire character, Edward Cullen, in the fall for the final two "Twilight" installments.
