50 Shades of Grey movie cast rumors are causing a lot of buzz on the Web. I'm afraid the speculation will continue until 50 Shades author E.L. James and Universal Studios confirm who will be cast as Anastasia Steele and Christian Grey.

Vampire Diaries star Ian Somerhalder is one of most visibly credible candidates to play sex maniac Christian Grey in the upcoming 50 Shades of Grey movie adaptation. His Vampire Diaries co-star Nina Dobrev is also rumored to play Ana. It could just be another bogus movie cast prediction. Nonetheless the decision wouldn't be too shocking, considering the two already have on-screen chemistry.

50 Shades of Grey fans have been making homemade trailers with clip mash ups of their dream cast scenarios. Check out this 50 Shades fan trailer of Ian Somerhalder casted as Christian Grey.

Here's a raunchy fan made clip of Stephen Ammell (Arrow) as Christian Grey in the upcoming 50 Shades of Grey movie adaptation.

Other potential Christian Grey cast members include Matt Bommer (White Collar) and Henry Cavill (Man of Steel).

Anastasia Steele cast possibilities are a little harder to pencil, seeing how the rumors fluctuate constantly. So far Alexis Bledel (Gilmore Girls), Emilia Clarke (Game of Thrones), Allison Williams (Girls), and obviously Nina Dobrev top the list.
