Actress Lynne Roberts began her film career in minor roles in 1936. Upon being signed by Republic, she co-starred with the studio's newest singing cowboy Roy Rogers. From 1939 to 1942, she was billed as Mary Hart, reportedly so that Republic could advertise their own "Rogers and Hart" screen team. During this period she was also a regular in the studio's Higgins Family series, co-starring with James, Lucille, and Russell Gleason. Upon moving to 20th Century Fox in 1942, she became Lynne (or Lynn) Roberts again, and remained so until her retirement in 1953.
