Keith Andes, 85, an actor with classic movie-star looks who considered his role as Marilyn Monroe's boyfriend in the 1952 film "Clash by Night" a highlight of his 30-year career, was found dead Nov. 11 in his home in Santa Clarita, Calif.

He had bladder cancer and several other ailments. The Los Angeles County coroner's office has ruled the death suicide by asphyxiation.

Although Mr. Andes was reticent about his career, the walls of his apartment were lined with memorabilia, including an album cover from "Wildcat," the 1960 Broadway musical in which he starred opposite Lucille Ball. A framed note from Ball alludes to their sharing close quarters on stage: "I ate onions, ha-ha, love, Lucy."

Mr. Andes came to Hollywood after studio head Darryl F. Zanuck saw the understudy perform in the Broadway production of "Winged Victory" and offered him a minor part in the 1944 film version.

The actor with the soothing baritone went on to appear in about 20 other movies, including playing one of the brothers in "The Farmer's Daughter" (1947) and Gen. George C. Marshall in "Tora! Tora! Tora!" (1970).

On television, he starred as an amateur sleuth in "Glynis," a 1963 CBS sitcom in which Glynis Johns played his wife, and in the syndicated police drama "This Man Dawson" from 1959 to 1960. He also made guest appearances on more than 40 shows, many of them westerns.

He was born John Charles Andes in Ocean City, N.J. By 12, he was performing on the radio.

He graduated with a bachelor's degree in education from Temple University in 1943 and studied voice at the Philadelphia Conservatory of Music.

During his three years in the Army Air Forces, he sang and acted in USO shows, including performing in South Korea.

After World War II, he appeared on Broadway in "The Chocolate Soldier" -- earning the Theatre World Award for the outstanding breakout performance of 1947 -- and later starred in "Kiss Me Kate."

In 1967, he played Don Quixote in a touring production of "Man of La Mancha" and kept in his living room a trunk he used while traveling with the show.

He bought a house in the 1950s and kept Arabian horses on a three-acre ranch in Chatsworth, Calif., which then was considered far from Hollywood.

"Making trade talk on movie parties" wasn't for him, he told the Los Angeles Times in 1957. "My family and I are satisfied to be on 'the Western kick.' "

After retiring in the late 1970s, Mr. Andes did voice-over work but spent many of his days riding his motorcycle throughout the West.
