The movie cowboy may be all but extinct, but that doesn't stop former screen star Rex Allen from keeping busy at age 67.

Allen, who lives in a prefab log house in a rural section of southern Arizona near Sonoita, continues narrating commercials and nature specials.

Allen, who was invited to Hollywood in 1950, said he always knew he'd probably be the last of the big-screen cowboys, for television had arrived and Western movies were already heading into the setting sun.

"I was the last of the Mohicans," he said recently. "Roy Rogers was leaving the studio, Republic, after more than 100 pictures, because he wanted to do television and the studio wouldn't let him do it.

"They were grooming me to take his place, and I did the last 36 (Western) pictures that they ever made."
