The Fifty Shades of Grey movie has finally cast the role of Christian Grey's mother.

According to Variety, Marcia Gay Harden has been cast as Dr. Grace Trevelyan Grey. She is the adoptive mother of Christian Grey, played by Jamie Dornan, his sister Mia Grey, who will be played by British singer-songwriter Rita Ora, and Elliot Grey, played by Luke Grimes.

Harden just wrapped up filming Magic in the Moonlight, Wood Allen's newest film, The Hollywood Reporter reports. You might also recognize the actress from HBO's "The Newsroom" and ABC's "Trophy Wife."

The casting of Dr. Grey represents one of the last major roles in the film to be filled. A couple more characters remain open, such as Elena Lincoln, also known as Mrs. Robinson. Elena is an old friend and business partner of Christian and the origin of Christian's S&M obsession. She taught Christian about chains and whips when he was just 15-years-old.

Whoever is cast as Elena will join a Fifty Shades of Grey cast that is looking more solid since the departure of Charlie Hunnam as Christian on Oct. 12. Dakota Johnson happily accepted the lead female role of Anastasia Steele. Max Martini joined the cast as Jason Taylor, Christian's bodyguard. Eloise Mumford will play Kate Kavanagh, Anastasia's roommate. "Pride and Prejudice's" Jennifer Ehle is Anastasia's mother. Meanwhile, Victor Rasuk has been cast as Jose, a photographer who dreams of making romantic Kodak moments with Anastasia.

Sam Taylor-Johnson is the director of the Focus Features and Universal Pictures movie. Michael De Luca, Dana Brunetti and E.L. James, the author of the erotic novel from which the movie is based, are producers.

Production for the film began on Monday in Vancouver, Canada. (The Fifty Shades of Grey novel takes place just south of Seattle, Washington.) Various photos snapped by paparazzi showed Dornan dressed in true Christian Grey style, like the kinky, wealthy, sex fiend he is. The "Once Upon a Time" actor was seen in a black three-piece suit with a flashy timepiece on his wrist. Meanwhile, Johnson morphed into Anastasia Steele. The 21 Jump Street actress wore an army-green denim jacket, fashionable scarves and, of course, her newly brunette hair.

Fifty Shades of Grey will be released just in time for Valentine's Day on Feb. 13, 2015.
