Marcia Gay Harden, currently co-starring as Christian Grey’s mom in Fifty Shades Of Grey, has been cast in CBS pilot Code Black, a medical drama eritten by Intelligence creator Michael Seitzman and directed by David Semel. Based on Ryan McGarry’s feature documentary of the same name, the drama series — like the docu — is set in the busiest and most notorious ER in the nation – LA County Hospital – where the extraordinary staff confronts a broken system in order to protect their ideals and the patients who need them the most.

Harden will play Christa, a former soccer mom whose son died of cancer. She is now a newly minted, talented and dedicated doctor whose experience handling her son’s disease, coupled with her intuition and life experience, makes her see things that often escape her much younger fellow residents. Harden, repped by ICM Partners, Framework, and Schreck, Rose, also recurs on ABC’s How To Get Away With Murder.
