Vanessa Redgrave Joins ABC's 'The Black Box'

Vanessa Redgrave is headed to ABC's "The Black Box."

According to The Hollywood Reporter, the Oscar winner has joined the series as Dr. Hartramph, psychiatrist to Elizabeth Black's (Kelly Reilly) renowned neuroscientist, and the only one who is privy to all of Elizabeth's secrets.

The series centers on Elizabeth, a woman who outwardly seems to have it all but internally struggles with mental illness -- which is one of many secrets she strives to keep from her friends and family.

Famous for her roles in "The Butler" and "Julia," Redgrave's recent TV stints include "Call The Midwife," and "Political Animals."

"The Black Box" has a 13-episde order, but ABC has yet to set a premiere date.
