Fans are starving to know who will play the key role of Christian Grey in the hotly anticipated upcoming movie "Fifty Shades of Grey."

The steamy "Fifty Shades" trilogy, written by bestselling author E.L. James, tells the story of 22-year-old recent college grad Anastasia Steele, who enters into a dominant/submissive sexual relationship with 27-year old sexy billionaire Christian Grey, through an "agreement," and both explore the world of BDSM (bondage, dominance, submission, masochism).

According to Gather Entertainment, Christian needs to be played by someone who has the ability to portray a character with a dark past.

"Christian definitely needs to be clean-cut, but extremely sexy when disheveled," Alison Genet of Twifans.com told MTV News. "I wouldn't choose a man that is overly chiseled. No juicehead gorillas need apply. Hair that can be neatly brushed, but when playing, it's loose and wild like Johnny Depp hair. Not super short."

Let's take a closer look at the Books & Review top 10 favorite star list.

1. "The Vampire Diaries" star Ian Somerhalder, 33

Somerhalder, who plays Damon on the sexy vampire TV show, has been showing that he wants to play the role of 27-year-old Christian. Last month, he even held a sort of campaign on his Twitter, making it clear that he's more than qualified to take the role, according to The Hollywood Gossip. Fans are dying for him to be the one. One commenter said, "It has to be Ian Somerhalder!" Another said, "Only Ian Somerhalder can pull off that look of Christian Grey!"

2. "Immortals" star Henry Cavill, 29

Cavill has always been on the Christian Grey fan list. He played Theseus in "Immortals" and will star as Clark Kent in upcoming movie "Superman." Fans are screaming for him. One commenter said, "Henry Cavill is pure perfection." Another simply said, "HENRY CAVILL!!! He's Christian Grey!"

3. "Snow White and the Huntsman" star Chris Hemsworth, 28

He read the book, and fans want him to play the key role of Christian too. Earlier this year, Hemsworth sat down with MTV, along with the cast of "Snow White and the Huntsman" and seemed a adorably embarrassed by the whole talk of "Fifty Shades of Grey." Fans want him anyway. One commenter said, "Chris Hemsworth is Christian Grey for me. He has that look that can go many ways." Another said, "I only see Chris Hemsworth when I read it!"

4. "White Collar" star Matt Bomer, 34

Bomer has always been in the Christian Grey race. He stars as Neal Caffrey in "White Collar" and fans are drooling over him. One commenter said, "Yes Henry Cavil is a good choice but have you seen Matt Bomer. He is my Christian Grey." Another said, "Matt Bomer definitely."

5. "True Blood" star Alexander Skarsgard, 35

This actor has been on the list from the beginning. At Comic-Con San Diego 2012, he revealed to fans that he hasn't read the book nor has he been offered a casting part. Maybe raving fans could change the producer's minds. One commenter said, "I only picture Alexander Skarsgard as Christian. I saw him as it the first time I read it." Another said, "i agree Alexander is the one and only Mr. Grey. He has sexuality and a presence on screen that just comes natural. For me, there is no one else. Give him the script already!"

6. "Supernatural" star Jensen Ackles, 34

Ackles has been newly added to the Christian Grey boat. According to What Culture, Ackles is listed as number one on their list of ten actors that should play mysterious Christian Grey. "Ackles would bring the necessary dark mystique, and he is another actor who has been suggested by fans," What Culture wrote. "He would certainly be a marketing savvy pick, because fans of Supernatural have been calling out for the opportunity to see him in a more erotic role for some time now." One fan said, "I would see this movie 100 times if they cast jensen ackles!!!" Another said, "Jensen Ackles ! no contest !"

7. "Drive" star Ryan Gosling, 31

Voted as the 2011 sexiest man on the planet, Gosling was in first place during the race for which star to play Christian Grey. "The role of the sadomasochistic billionaire seems to be man-of-the-moment Ryan Gosling's to turn down. But the 'Drive' star may take some persuading," The Sun newspaper claimed. Maybe fans can persuade him too. One commenter said, "Ryan all the way! He is exactly who I pictured while I was reading the book." Another said, "Ryan, Ryan, please choose him. He is perfect fit!"

8. "Magic Mike" star Channing Tatum, 27

Tatum recently put himself up for the role. When asked if he would play the protagonist in the adaptation in an interview with U.K. Glamour Magazine, he responded: "1) Yes. 2) I'd only be allowed if my wife was Ana. She's read the books so I don't think she'd be impressed if she couldn't be Ana!" What do fans think? One commenter said, "I would love to see Channing Tatum get the roll." Another said, "I would be so thrilled to see the dark side Channing Tatum would play..."

9. "Star Wars" star Hayden Christenten, 31

Known for his role as Anakin Skywalker "Darth Vador" in some episodes, fans are in love with him because of his attractiveness and his blue eyes. One commenter said, "Hayden Christensen is 100% perfect for this role. That face, those eyes, that grin, he has a serious side but also a playful side." Another said, "Matt Bomer or Henry Cavill. Or Hayden Christensen."

10. "Dancing with the Stars" William Levy, 31

Levy is newly added to the hot list of stars. According to Extra TV, "Dancing with the Stars" fans went crazy for telenovela star Levy. His shirtless moves last season were the talk of the ladies. The showing off of his hot bod might win him the role of sexy billion Christian Grey. He revealed to Extra's Mario Lopez that he has already read the books. He said, "I like the book, actually. I think all guys should be like that." And fans think Christian Grey should be like him. One commenter said, "William Levy embodies the complete fantasy male lead role and essence that is Christian Grey." Another said, "William Levy as Christian Grey = Perfection."
