Ryan Gosling: Universal and Focus have been tight-lipped about any actors they have in mind to play the kinky Mr. Grey, but Mr. Gosling's many admirers have not stopped talking about the possibility. He was a romantic in "The Notebook," a romantic murderer in "Drive," and a kind-of-sort-of romantic bank robber in "The Place Beyond the Pines."
Matt Bomer: The handsome "White Collar" star isn't under official consideration to portray Christian Grey so much as fans have openly demanded it. He's been a top choice on polls all over the web, been featured in fan-made trailers and even graced the cover of a fake Entertainment Weekly cover announcing him as the "50 Shades" lead.
Zac Efron: Another Hollywood hunk whose name has been tossed into the "50 Shades" arena by his fans. Why? Because why not?
Emma Watson: The 23-year-old may be shedding her "Harry Potter" image by starring in Sofia Coppola's "The Bling Ring," but she's not ready to shed her clothing in "50 Shades." She put an end to rumors she had been cast in March by tweeting: "Who here actually thinks I would do '50 Shades of Grey' as a movie? Like really. For real. In real life. Good. Well that's sorted then."
Henry Cavill: It's a bird, it's a plane, it's Superman -- and another actor fans are rallying behind to be cast as the man of many whips and chains. Like Matt Bomer, he's also been featured in plenty of fan-made trailers depicting their "50 Shades" dream team.
Mila Kunis: As much as the world wide web wants her to, this movie star doesn't want any part of "50 Shades of Grey." The "Ted" actress put rumors to bed in March during a press conference for "Oz the Great and Powerful" when she said, "No, you will not see me in Fifty Shades of Grey. I'm so sorry." Despite the blunt statement, she's still topping internet polls as the perfect Anastasia Steele incarnate.
Emilia Clarke: Daenerys Targaryen bows down to no man except Khal Drogo, but this "Game of Thrones" star's fans would like to see her get spanked by Christian Grey. Nearly 80,000 YouTube users have watched her steam it up as Ms. Steele in a fake trailer co-starring old footage of Henry Cavill. Some websites have been busy running the rumor mill by "reporting" in April that she has signed on for the role.
Allison Williams: She's a girl who plays a girl in her 20s on "Girls," which, apparently, makes her the perfect fit for the role of a 21-year-old girl Anastasia Steele. Williams, however, has no intention of making rumor reality. "I wouldn't take it," she told Fashion Magazine last summer. "It is just too much for me but I applaud whatever actress steps up to the plate and I can't wait to watch it."
Ian Somerhalder: The "Vampire Diaries" star has been on "50 Shades" fans' radar since he told Ryan Seacrest in April of 2012 that he would portray Christian Grey "beyond the shadow of a doubt." Months later, the actor revealed that comment was nowhere near official and tweeted: "Ok, this Christian Grey thing has gotten out of control. Know this, I'm not 'desperate' to do anything except relax today."
Lucy Hale: Ever since the "Pretty Little Liars" star told the press that playing Anastasia Steele "would be freaking awesome," she's been featured on a ton of website polls asking readers to weigh in on their dream cast. And good news for Somerhalder: "Looks-wise, he's a good one," Hale has said.
Nina Dobrev: As Ian Somerhalder's real-life girlfriend and "Vampire Diaries" love interest, it's only logical that she'd be in the hypothetical running to be his on-screen love interest in "50 Shades of Grey," too.
Stephen Amell: Another CW star that has expressed interest in taking on the role of Christian Grey, but the "Arrow" actor has claimed he's in talks to star: "I get questions about Christian Grey all the time. That project is a long way off. I know this because I had a meeting about it. Long way off. I mean, not that long, but not close. I wouldn't call it long, but I wouldn't call it close."
Alexander Skarsgard: Another vampire rumored to be taking the lead in "50 Shades." Some fans are so gung ho about his casting that they've created a Facebook community page citing "those soul searching eyes along with mystery, intensity, humor, killer grin and maturity" as reasons he's a perfect fit for the role.
Michael Fassbender: The young Magneto had no problem showing off his goods in "Shame," so it was inevitable he'd be a top pick for a "50 Shades" adaptation. As of last summer, however, he had never heard of the source material. "I don't even know what that is," Fassbender told the Sun Times. "I've heard people saying stuff about my casting and it's on the Internet ... Nobody has approached me."
Kristen Stewart: "50 Shades" started as a piece of "Twilight" fan fiction, so it's not hard to imagine why Stewart was and maybe always will be rumored to be playing Anastasia Steele. Unfortunately for "50 Shades" fantasy casting brackets, Stewart has said she is "genuinely creeped out" by the book series and is even more creeped out by people reading it on a plane with a blanket over their lap.
Shailene Woodley: The "Descendants" supporting actress is on the cusp of becoming a major star as Mary Jane Watson in "The Amazing Spider-Man 2." According to rumors, she is said to have caught the eye of Fifty Shades of Grey author E.L. James.
Alexis Bledel: This "Gilmore" girl has also been pre-cast by as Anastasia Steele by fans. She appears in a fake trailer opposite another fan favorite: Matt Bomer.
Erik Odom: Best known for a small role in "The Twilight Saga: Breaking Dawn - Part 2," this actor is the latest rumored to be in the running for the Christian Grey role. Why? He was spotted tweeting back and forth with author of "50 Shades" herself, E.L. James.
Emmy Rossum: According to People.com, 26-year-old Rossum is perfect for the role. Then again, so are a lot of actresses in the 20s who have brown hair, a pair of eyes and like big pay checks.
Chris Pine: This generation's Capt. Kirk has gone as far as to say he would be interested in the role "if it's a good script." That's enough indication the internet needs to assume he's in talks with the studio. However, Pine took himself out of the running last summer when he told Jay Leno, "I'm not doing it, no."
