Having emerged from the heady days of the free-spirited 1960s, actress Margot Kidder became instantly famous for her fiery take on Lois Lane opposite Christopher Reeve in "Superman: The Movie" (1978). Prior to her career-defining role, Kidder made her first major film with former beau, director Brian De Palma, in "Sisters" (1973), though she struggled for several years until playing Lane. She followed up with "The Amityville Horror" (1979) and reprised Lois Lane for "Superman II" (1981), only to see the studio cut down her role to the bare minimum for "Superman III" (1983). Meanwhile, Kidder lived quite the colorful life off screen, marrying multiple times - including actor James Heard for a mere six weeks - while having dalliances with De Palma, Steven Spielberg and Richard Pryor. Kidder privately battled bipolar disorder throughout her life, but suddenly found herself the center of unwanted attention in 1996 when she publicly had a manic episode that lead to her being discovered disheveled in a cardboard box with a homeless man. In being forced to confront her problems, however, Kidder finally overcame her illness and found something resembling peace, as she continued to appear onscreen in films like "Halloween II" (2009) while proving herself to be a true survivor.
