Richard Widmark, who made a sensational film debut as the giggling killer in "Kiss of Death" and became a leading man in "Broken Lance," "Two Rode Together" and 40 other films, died Monday. He was 93.

Widmark's wife, Susan Blanchard, said he died at his home in Roxbury after a long illness. She would not provide details of his illness.

Widmark earned an Academy Award nomination for best supporting actor for his role in the 1947 thriller "Kiss of Death." He played Tommy Udo, who delighted in pushing an old lady in a wheelchair down a flight of stairs to her death. It was his only Oscar nomination.

A quiet, inordinately shy man, Widmark often portrayed killers, cops and Western gunslingers. But he said he hated guns.

Rejected by the Army because of a punctured eardrum, Widmark began appearing in Broadway plays in 1943. His first was a comedy hit "Kiss and Tell." He was appearing in the Chicago company of "Dream Girl" with June Havoc when 20th Century Fox signed him to a seven-year contract. He almost missed out on the "Kiss of Death" role.

Widmark appeared in 20 Fox films from 1957 to 1964. After leaving Fox, Widmark's career continued to flourish. "Madigan," a 1968 film with Widmark as a loner detective, was converted to television and lasted one season in 1972-73. It was Widmark's only TV series.

He also was in some TV films, including "Cold Sassy Tree" and "Once Upon a Texas Train."

In later years, Widmark appeared sparingly in films and TV.
