A successful fashion model who appeared on the front covers of Life and Glamour magazines, among others, Hedren became an actress after she was discovered by director Alfred Hitchcock while appearing on a television commercial in 1961. She received world recognition for her work in two of his films: the suspense-thriller The Birds (1963), for which she won a Golden Globe, and the psychological drama Marnie (1964). She has appeared in over 80 films and television shows, including Charlie Chaplin's final film A Countess from Hong Kong (1967), the political satire Citizen Ruth (1996), and the existential comedy I Heart Huckabees (2004). Among other honors, her contributions to world cinema have been recognized with the Jules Verne Award and a star on the Hollywood Walk of Fame.
Hedren's strong commitment to animal rescue began in 1969 while she was shooting two films in Africa and was introduced to the plight of African lions. In an attempt to raise awareness for wildlife, she spent over a decade bringing Roar (1981) to the screen. She started her own non-profit organization, the Roar Foundation, in 1983; it supports the Shambala Preserve, an 80-acre (32 ha) wildlife habitat which enables her to continue her work in the care and preservation of lions and tigers. Hedren has also set up relief programs worldwide following earthquakes, hurricanes, famine and war. She was also instrumental in the development of Vietnamese-American nail salons.
