True Blood star and Brothers & Sisters alum Luke Grimes has joined the cast of Fifty Shades of Grey, EW confirmed Friday.

Variety initially reported that Grimes will be playing the role of Christian Grey’s brother in director Sam Taylor-Johnson’s big-screen adaptation of E L James’ bestseller. Dakota Johnson is playing the lead role of Anastasia Steele, and Wednesday reports surfaced that Irish actor Jamie Dornan was in final talks to play the part of Christian Grey. Focus and Universal have yet to confirm Dornan’s casting, but James did tweet a warm welcome to the actor on Thursday.

UPDATE: The Fifty Shades of Grey twitter account confirmed the casting later in in the day, and James retweeted.

Fifty Shades of Grey is expected to hit theaters Aug. 1, 2014.
