Margo Martindale – Started At Age 53

Margo Martindale made her cinematic debut in 1990; for the next several decades, she was cast in supporting roles for TV and movies. In 2004, at 53, her name became more widely known when she played Big Mama in Broadway’s “Cat on a Hot Tin Roof” production.

Soon after, Margo started to take on more excellent roles, including a recurring character on the show “BoJack Horseman,” which is an exaggerated version of her real-life persona.
