One man who is yet to comment on the ever growing speculation, and his growing fan base, is 'The Dark Knight' star Christian Bale. Despite being about 10 years older than Mr Grey in the books, Bale has got the dark, mysterious persona down to a T; you've seen him in 'American Psycho' right? Not to mention he is still extremely handsome. There is even a fan made movie trailer featuring Bale as Mr Grey which has racked up almost 500 thousand views on 'YouTube'; all these fans cannot be wrong.

The 'Spring Breakers' and 'Oz - The Great and Powerful' star may be as versatile as he is hot, but with that cheeky grin, would he be able pull off the role of serious, seductive Mr Grey? There is only one way to find out! The actor has already shown an interest in the role, stating at the Sundance Film Festival "It sounds interesting...I'd do it." So EL James and director Sam Taylor-Johnson, it's your move!
