The funny thing about this rumored "Fifty Shades" sex scene test footage - Van Sant (the mastermind behind films like "Good Will Hunting" and "Milk") hasn't even been named the official director yet! Looks like he's pulling out all the stops to snag the coveted title... and he's bringing 23-year-old Pettyfer along for the kinky ride! The handsome British actor/model plays the charming, sexually dominant Mr. Grey in the short clip - the actress who portrays Steele still remains unknown.

Do fans think Pettyfer has what it takes to secure the passionate, BDSM-heavy role of Mr. Grey? Check out this sexy "Fifty Shades" compilation and decide for yourself... how does he compare to fellow fan-favorites Ian Somerhalder, Matt Bomer, Henry Cavill, etc?

Pettyfer definitely isn't afraid to shed his clothes in front of the camera, and he has a drool-worthy body that many "Fifty Shades" fans would probably appreciate!

And as for Anastasia Steele... several gossip reports suggest that Jennifer Lawrence is currently E.L. James and filmmakers' "number one choice." According to an alleged insider for Hollywood Life, "If producers can have it their way, J-Law will play Anastasia Steele in the 'Fifty Shades of Grey' films."

It's true - with her naturally fresh beauty and girl-next-door persona, the 22-year-old Oscar-winning actress could indeed make the perfect Miss Steele. Celebrity photographer Chris Kaufman (who recently revealed an intimate series of photographs of Lawrence) claims that she "has a maturity beyond her years" -

"'When I first took her picture, I stopped shooting and I turned to my assistant and said, 'You don't see people move like that'... I was thinking she moved like Gisele [Bündchen], and I've seen Gisele in person. It was like, 'Where did you get this ability?' She's not going to care what she says, and the charm of her is that she will tell you what she's thinking. She will totally slip up one day and say something ridiculous but totally overcome it."

Still, fans shouldn't always be quick to believe everything they read. Hollywood Life has sensationalized "Fifty Shades" casting rumors for months. The webloid claims that both Lawrence AND Pettyfer have been officially confirmed for the "Fifty Shades" movie, and filming will begin in London next summer. That's not exactly true... absolutely nothing's been confirmed (yet).

Still fun to fantasize about! So what do "Fifty Shades" fans think...
