Casting rumors about the coming film adaptation of "Fifty Shades of Grey" are everywhere and constantly changing.

Last week, it appeared as if "Harry Potter's" Emma Watson was a top contender for the part of Anastasia Steele, until the young actress insisted she hadn't even read the book, let alone a script.

As fans get restless for the official word on who will play their favorite characters, some are even creating their own mock-up trailers, including one popular video starring Matt Bomer and Alexis Bledel.

But the film's casting director's search might be over, because two extremely popular actors recently did a short reading of the text and seemed to have real finessed it.

During a promotional interview for their coming movie "The Campaign," Will Ferrell and Zach Galifianakis were asked to try on the roles of the literary dominant and submissive, as noted by Gawker.

It's hard to say for sure with so many talented actors likely vying for the parts, but I think this pair nailed it. Of course, it would be hard not to give a satisfyingly erotic performance with that mood music.
