The "Fifty Shades of Grey" movie production will have huge expectations to meet, considering the massive number of fans who have been anticipating the film adaptation of E.L. James' erotic bestseller series. But first (among many other "first" priorities), they have to cast the characters right.

Some fans have their respective Christian Grey and Anastasia Steele-Grey in mind. Others have couples pictured for the roles. White Collar's and Magic Mike's Matt Bomer and Gilmore Girls' Alexis Bledel have their own fan base. Real life sweethearts Ian Somerhalder and Nina Dobrev, both enjoying "Vampire Diaries" fame, have their own following. Superman Henry Cavill is being paired to Emilia Clarke aka Daenerys Targaryen of the Game of Thrones. Who makes the best "Fifty Shades" movie couple among them all?

Matt Bomer and Alexis Bledel as Christian Grey and Ana Steele. Bomer suited up with the quietly vibrant Bledel looks great in photos. Instagram is filled with photos of these two, and the chemistry in each photo cannot be ignored.

Ian Somerhalder and Nina Dobrev. The recent Entertainment Weekly cover of this couple blends the purity of white into their blazing appeal. The result shows a potentially intense presence as BDSM couple. Lucy Hale of "Pretty Little Liars" is also being paired to Somerhalder, but the EW cover is quite hard to beat.

Henry Cavill and Emilia Clarke. Who doesn't want to see Superman and super dragon momma together? Cavill and Clarke are both competent actors. They will both shed their superhero and GOT skins for "Fifty Shades," no doubt. But to the fans, this couple will channel their inner superhero and super (rightful) queen powers to unleash all levels of passion for what is going to be a very raunchy film. And they'll look great together.

Who do you think will look great (and act great) as Anastasia Steele and Christian Grey?
