Casting Fifty Shades of Grey

My thoughts on who will play the main characters in what will inevitably be the movie version of Fifty Shades of Grey...

In no particular order, the person I see as the 27 year old, copper haired, grey eyed, billionaire CEO & Domineer, Christian Grey?  Chace Crawford, Jeff Buckley or Christopher Pine.

And the awkward,  submissive, Anastasia Steele?  Elizabeth Olsen, Emma Watson or Shenae Grimes.
