Variety reports that "True Blood" actor Luke Grimes -- who played James, Jessica's love interest on the HBO vampire drama -- has been cast as Elliot Grey, Christian's brother. The news comes on the heels of Jamie Dornan replacing Charlie Hunnam as the movie's main protagonist.
In the erotic novel by E.L. James, Elliot goes along with Christian when he picks up a drunk Anastasia (to be played by Dakota Johnson) at a bar. There, he meets and flirts with Anastasia's friend Kate (yet to be cast). Elliot is also a part of the book's sequels.
Grimes is an up-and-coming actor who's had small parts in "Brothers and Sisters" and "Taken 2." Once director Sam Taylor-Johnson fills out the rest of the cast, filming is set to begin in the next few weeks.
"Fifty Shades of Grey" is set to hit theaters August 1, 2014.
