Best known for her iconic Oscar-winning role as Scarlett O'Hara in Gone With the Wind, Vivien Leigh also captured the public's attention with her marriage to fellow actor Laurence Olivier. However, Leigh was diagnosed with bipolar disorder and her unpredictable behavior eventually ruined her professional reputation and destroyed her marriage to Olivier.
"In her day there were no pills, there were no clinics, there were no publicists, there was nobody between Vivien and an outside world which she found chilly, hostile, and sometimes, because of her mental state, could not cope with," said her friend Sheridan Morley in a BBC documentary.
Carrie Fisher's portrayal of Princess Leia in the original Star Wars trilogy turned her into a pop-culture icon. However, partly due to her tumultuous childhood, she struggled with drug and alcohol addictions. In her early 20s, Fisher was told she was hypomanic, but she didn't believe her doctor.
Over time, however, she came to terms with her condition and became a bestselling author in the process, writing books such as Postcards From the Edge and Surrender the Pink. Becoming a mother was the impetus for this change.
"Prior to having a child, I really did feel, it's my business if I wanted to stop my medications," she tells bp Magazine. "I no longer feel that's so."
