Bella Heathcote is joining the “Fifty Shades of Grey” family. Series author E.L. James announced on Twitter Friday that the actress will be starring as Christian Grey’s (Jamie Dornan) former and mentally unstable submissive in the 2017 sequel, “Fifty Shades Darker.”

While fans were thrilled by James’ casting announcement, Heathcote isn’t as well-known as some of her “Darker” co-stars. So, just who is the actress? A quick look at her filmography shows she’s had a impress career thus far. Her most notable roles to date include a part in Johnny Depp’s 2012 comedy “Dark Shadows” and the 2011 action movie “In Time,” which starred Justin Timberlake.

Heathcote, 28, also stars as Jane Bennet in the newly released zombie thriller “Pride and Prejudice and Zombies.” Her next feature, the horror/thriller “The Neon Demon," stars Elle Fanning, Keanu Reeves and Christian Hendricks and is due to premiere later this year. 

While she may not be a household name, Heathcote isn’t new to the acting scene. According to her IMDb profile, she’s won two awards in her career. The site credits her with winning Breakthrough Performer at the 2012 Hamptons International Film Festival and the Spotlight Award at the 2012 Hollywood Film Awards for her role in “Not Fade Away.”

Heathcote isn’t the only new cast member to join the “Fifty Shades” trilogy. Last month, James revealed that veteran film star Kim Basinger would be playing Christian’s former BDSM partner Elena Lincoln/Mrs. Robinson. 

“Fifty Shades Darker” is due to start production in Vancouver on Feb. 16. The movie premieres in theaters Feb. 10, 2017.
