No one has definite information about casting for the two lead roles in the upcoming "Fifty Shades of Grey" movie.

However, fans already know who they want to play sexy billionaire Christian Grey.

Many actors are on the growing list of stars, which include well-known actors such as "The Vampire Diaries" star Ian Somerhalder, "White Collar" star Matt Bomer, "Twilight" star Robert Pattinson, "True Blood" star Alexander Skarsgard, and "Superman" star Henry Cavill.

However, some fans want to see an unknown actor play the steamy part of Christian.

One possibility could be model Noah Mills.

According to his IMDb profile, Mills started modeling in 2003. He was featured in Gucci, Yves Saint Laurent, Calvin Klein, Emporio Armani, and featured on many covers of magazines as well as several ad campaigns and catalogs.

He also has an acting side though. In 2010 he started as Nicky who was Samantha's new love interest in "Sex and the City 2."

He also started in "2 Broke Girls" in 2011.

Many know the star for his abs and lips. Maybe that is why fans want Mills to play the important role of Christian Grey. He's also 27-years-old, which is Christian's age exactly.

One commenter on PerezHilton.com wrote, "Actor/Model Noah Mills should be Christian Grey. Google the name, he is perfect for that role."

Mills is also featured on Topsy.com as Christian Grey. A fan posted a photo of him on the Facebook page "Meet Me In The Red Room" saying "I wish Christian Grey will be played by Noah Mills or Henry Cavill."

Another unknown actor is TJ Dalrymple. Many "Fifty Shades" fans already know him because of his acting. He plays Christian Grey in a "Fifty Shades of Grey" fan-made film, "We Aim to Please." The actor played in some short films, according to his IMDb page.

On his website, Dalrymple says about him, "The driving force in my life has always been creativity. Whether its creating a character, picture, sculpture, hot rod or race truck, I'm fascinated by the possibilities of the imagination."

An unknown actress up for the role of Anastasia Steele is Lauren Watson.

The Examiner recently did an interview with Watson about the upcoming "Fifty Shades of Grey" movie. She's off to a good start.

"Yes, I have read the books! I didn't know anything about them and one of my friends said GO! NOW! Get the books and read them today!' I couldn't argue with that! I got them and read them all within the week! I was hooked," Watson said.

When asked about her fans and if she would consider the role of Ana, she said, "I've heard! The fans have been absolutely amazing! It is definitely a role I would consider."

Her IMDb page doesn't give away much information about the unknown actress. She played Sweater Set Girl (as Lauren Dowe) in "This Means War." She also played Themis in "13 Witches.

The "Fifty Shades" trilogy ("Fifty Shades of Grey," "Fifty Shades Darker," "Fifty Shades Freed"), written by 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 billionaireChristian Grey, and both explore Christian's world of BDSM while trying to understand their complicated relationship.
