Hollywood is certainly overflowing with cute and hot couples. With this in mind, producers of "Fifty Shades of Grey" will definitely find it easy to cast leads for the roles of Christian Grey and Anastasia Steele. Take one couple and cast both which would make everything easier and faster but of course it's best to pick the most suitable pairs to star in the film.

Obviously, it's taking a while for Universal Studios and Focus Features to announce an official cast for the highly-anticipated debut of the "Fifty Shades of Grey" film. With a director still not seated and a script in the works, fans are unlikely to hear casting news any time soon.

Of course, leave it to everyone else to speculate on the casting from naming one actress and actor to the next. Currently, over a hundred actors and actresses plus models have been named potential stars to portray the lead roles of Christian and Ana.

One favourite to the next have also been nominated on countless lists. Currently in the lead to play Christian Grey is Ian Somerhalder while in the lead to play Anastasia Steele is Emilia Clarke. So, it would be appropriate to pair Ian with Emilia given their both favourites for the role but would there be chemistry on screen if chances are these two get cast?

To greatly minimize the problems of casting separate stars for the role, why not cast real life couples to play the role of Ana and Christian? With countless cute, sexy and hot couples in the business, it wouldn't be difficult to find a pair suited for the parts of the S&M film.
