Francis Gregory Alan Morris (September 27, 1933 - August 27, 1996) was an American television and movie actor.

Born in Cleveland, Ohio, Morris began his acting career in the 1960s making guest appearances on many TV shows such as The Twilight Zone and Ben Casey. In 1966, he was cast in his most recognizable role as the electronics expert Barney Collier in the TV series Mission: Impossible. Along with Peter Lupus and Bob Johnson, he would be the only other actor to remain with the series throughout its entire run.

While in college, Morris was active in theater and hosted the late afternoon Jazz radio show, "Tea-Time" on the University of Iowa's station, WSUI. He co-produced concerts at the University with a student friend. After Iowa, Greg's first professional stage role was in The Death of Bessie Smith. One of his earliest television roles was on The Dick Van Dyke Show, when Rob and Laura think they've gotten the wrong baby from the hospital.

After Mission: Impossible was cancelled, Morris would appear in movies and make guest TV appearances before he was cast as Lt. David Nelson during the second season of the TV series Vega$. After the cancellation of the series in 1981, Morris would continue to make guest TV appearances in the next decade, including a few episodes in the short-lived 1980s remake of the Mission: Impossible TV series, which starred his son Phil Morris, who was cast as Grant Collier, the son of Barney.

Morris died in 1996 of brain cancer in Las Vegas, Nevada. Shortly before his death, he went to see the film version of Mission: Impossible that starred Tom Cruise. The reports were that he hated the movie so much (an opinion that was shared by several of his former co-stars) that he left the theater early.http://www.cnn.com/SHOWBIZ/9605/29/imposssibles/index.html
