Rennie, who TV fans may recognize from his stint on "Battlestar Galactica," will play Ray Steele, who Ana's mother Carla (played by Jennifer Ehle) married after Ana's biological father died. Ana took Ray's last name, though the marriage didn't last; actor Dylan Neal was recently cast to play Carla's current husband (and Ana's new stepfather), Bob.
Ray's character also provides a link to Ana's non-Christian love interest, Jose (Victor Rasuk), who's the source of some jealousy that fuels a few of Christian and Ana's S&M sessions. Ray and Jose's father served in the Army together.
"Fifty Shades of Grey," which stars Dakota Johnson and Jamie Dornan, hits theaters February 13, 2015.
