Dakota Johnson is already set to star as Anastasia Steele, with Sam Taylor-Johnson helming the pic.
Grimes will play Christian Grey’s brother, Elliot, in the film.
Michael De Luca and Dana Brunetti are producing. Kelly Marcel penned the script.
While the search is over for the main two leads — with Variety first reporting Jamie Dornan’s casting as Christian Grey — Uni and Focus still must find those remaining supporting roles, like Steele’s roommate Kate, and Grey’s bodyguard. While the roles aren’t as coveted as the two leads, they still could work as break-out parts for upcoming star like Grimes.
Grimes played Deborah Ann Woll’s new beau in the most recent season of “True Blood,” Grimes can be seen next in “The Shangri-La Suite.” Other past credits include ABC’s “Brothers & Sisters,” Fox’s “Taken 2” and the indie horror pic “All the Boys Love Mandy Lane.”
