LAS VEGAS (AP) _ Actor Greg Morris, who played quiet, efficient electronics expert Barney Collier in the ``Mission: Impossible'' television series, has died at age 61 after a recent battle with brain cancer.

Morris was found dead at home Tuesday. Clark County Coroner Ron Flud said today that Morris apparently died of natural causes, but no autopsy was planned.

Morris, who had fought brain cancer the past few years, told the Las Vegas Review-Journal in May that he was cancer-free.

In a 1994 interview, Phil Morris said his father continued to smoke while battling cancer that originated in his lung and later spread to his brain.

Morris was one of the first black actors to star in a hit series during the 1960s, playing a technical wizard on ``Mission: Impossible,'' which ran from 1966-1973.

``My seven years on that show were seven of the most fun years of my career,'' he recalled.

But he walked out of the new movie version after watching only 40 minutes.

``It's an abomination,'' he said of the Tom Cruise film, which did not feature any of the TV series' cast.

Born Sept. 27, 1934, in Cleveland, Morris went to Hollywood in the early 1960s after some minor stage experience in Seattle. He had guest roles on series including ``Dr. Kildare,'' ``The Dick Van Dyke Show'' and ``The Twilight Zone'' before being cast in ``Mission: Impossible.''

Morris played the part of an electronics expert who helped an elite team of agents usually involved in disrupting the activities of various small foreign powers seeking to create problems for the free world.

Morris came to Las Vegas in 1979 to film the TV series ``Vega$,'' in which he played Lt. David Nelson. He liked the city so much he decided to stay.

He and his wife, Leona, were divorced last year after 38 years of marriage. He is survived by three children: Phil, Linda and Iona.
