Pittsburgh-born James Newill attended the University of Southern California where he excelled in music and sports. After graduation, Newill appeared as a baritone singer in vaudeville and on radio. His first film was Grand National's Something to Sing About (1937), which led indirectly to his being starred in five Renfrew of the Royal Mounted adventure flicks. He went on to play frontiersman Jim Steele in Monogram's Texas Rangers Western series, in which he appeared from 1943 until his retirement in 1945. During his Hollywood heyday, James Newill occasionally sang in the theatrical opera company managed by another famous singing cowboy, George Houston.
