Now that Charlie Hunnam is officially not starring as S&M-loving hunk Christian Grey in the movie adaption of the hit erotica trilogy by E.L. James, we're playing casting director ourselves! Here are the top-seven famous duos we'd love to see as Anastasia and Christian.

Now that Charlie Hunnam is officially not starring as S&M-loving hunk Christian Grey in the movie adaption of the hit erotica trilogy by E.L. James, we're playing casting director ourselves! Here are the top-seven famous duos we'd love to see as Anastasia and Christian.

Prince Harry and Cressida Bonas

Harry is a natural redhead, just like Christian himself, so there’d be no hair dye required if Harry took the role! The prince also has a penchant for being naughty and clearly isn’t shy about dropping trou, as the naked photo of him in Vegas showed. His girlfriend Cressida is a former actress who appeared in the racy British show Trinity, in which she offered sexual favors in exchange for votes in a student election.

2. Rob Pattinson and Kristen Stewart

The whole 50 Shades trilogy was inspired by Twilight, so it would make perfect sense for Rob and Kristen to take on the title roles. We know the former couple already have serious chemistry, and both of them have been taking edgier, more mature roles lately. Plus, KStew already has the clumsy, awkward mannerisms of Anastasia down to a T. And who knows? Maybe playing love interests again would bring them back together in real life.

Katie Holmes and Tom Cruise

Katie’s got that sweet, innocent girl-next-door look, just like Christian’s love interest does. Her ex-husband Tom loves to be in control and starred in Eyes Wide Shut, a controversial movie about orgies and secret S&M sex parties. Not to mention, the Mission Impossible actor has already got the buff body for it!

Kanye West and Kim Kardashian

Just like Mr. Grey, Mr. West has that brooding, angry bad-temper thing down pat. The rapper will do anything to defend his leading lady and protect her from critics and paparazzi alike. Kim, who’s had guest-starring roles, already stripped down and posed totally nude for Playboy and just said she’d like to do another naked shoot now that she’s back to her pre-baby body. 50 Shades of Kimye, anyone?

Alexander Skarsgård and Kate Bosworth

The sexy Swedish actor’s name has been thrown around for the role of Christian before. The True Blood star, who played a vampire, has no issues with nudity. He’s already gone full frontal on his HBO series, and we wouldn’t mind seeing more of him on the big screen.

“Nudity is great,” he’s said. “If it makes sense in the script, I really don’t care.”

His former girlfriend could totally pass for a college student, too.

Ian Somerhalder and Nina Dobrev

The Vampire Diaries hottie actively campaigned for the role on Twitter, saying he’d “so love to be Christian Grey.” And we’d so love to see him in that infamous tie! Ian looks great shirtless, and his former girlfriend and current CW co-star would make a lovely Anastasia. The pretty pair have already proved they can make sparks together on screen in their hit series.

Brad Pitt and Angelina Jolie

The real-life power couple first played butt-kicking love interests in Mr. and Mrs. Smith, where we learned they’re not afraid to get rough with each other. Brad admits Angelina’s still a “bad girl” in the bedroom, so getting those kinky S&M scenes just right would be easy for them. The only issue we could see is all of her ink. She’d have to cover up her many tattoos to play Ana, who wouldn’t be caught dead getting one herself!
