Fans of "Twilight" sensation Robert Pattinson are about to see a whole different side of the British actor in an upcoming movie — quite literally a different side, in fact.

Pattinson stars in "Bel Ami," a period drama based on French author Guy de Maupassant's 1885 novel of the same name. The actor is playing Georges Duroy, a morally ambiguous journalist who gradually rises from rags to riches among the Paris elite thanks to his various connections to powerful and wealthy mistresses — a lineup of women played by Uma Thurman, Kristin Scott Thomas and other notable actresses.

In the past, Pattinson has described his character as "totally amoral" and very different than the types of roles his fans are used to seeing him inhabit. But despite this, it's hard to imagine the legions of Team Edward loyalists frowning at the news that Pattinson is showing off his bare backside for the period film.

"I think there's a lot of my crack in it," he laughed to MTV News while promoting "Eclipse," the latest "Twilight" installment. "I think there's quite a bit of nudity."

Pattinson said he still hasn't seen a final cut of the film, so whether his "crack" makes it into the finished version of "Bel Ami" remains to be seen. Regardless, the actor said working on the sex-filled period drama was quite a different experience, particularly as someone very used to the typically teen-friendly subject matter of the "Twilight" franchise.

"It was such a strange story," he said of "Bel Ami." "I think it will turn out to be very interesting, but I have no idea about any of it yet."
