Bette Davis took on the part of Margo at a time in her life when her reality perfectly mirrored the character she played. Davis was an extraordinary actress who, at the time, was standing face to face with the inevitable passage of time. Bette grabbed the character by the horns and rose to the challenge in an iconic performance that few can match. Source: IMDb.com
