By 1980, Channing's film career was idling in neutral, so she focused her energies on the theater, though she began showing up in various supporting film roles in the mid to late eighties.
In 1993, she was nominated for an Oscar and a Golden Globe for playing the formidable Upper East Side matron of Six Degrees of Separation; the role had also earned her a Tony nomination when she performed it in the film's stage version.
After filming Other Voices in 2001, which was screened at the prestigious Sundance Film Festival, Channing would receive a solid amount of critical success for her role in The Business of Strangers (2001), in which she starred as a high-level corporate player who saves her own job only to find out her boss is a rapist.
In the early '70s, Channing appeared in several small television roles, and made her big screen debut in 1971's The Hospital.
In 1973, the actress starred in the Joan Rivers-penned black comedy The Girl Most Likely To..., a TV movie about an overweight college girl who loses weight, gets cosmetic surgery, and sets off in hopes of getting even.
Several unsuccessful Broadway auditions later, she landed a lead role in a Los Angeles production of Two Gentlemen of Verona.
Born Susan Williams Antonia Stockard Channing Schmidt on February 13, 1944, Channing is the daughter of a wealthy shipping executive, and became interested in the dramatic arts while attending college at Radcliffe.
After graduating in the mid-sixties, Channing joined Boston's experimental Theater Company.
