Her next picture was the well-received drama The Human Comedy, which featured a star cast, headed by Mickey Rooney, Frank Morgan, James Craig and Marsha Hunt.

The Crime short turned out so well that MGM expanded it into a full-length feature, Main Street After Dark in 1945, for which the actress was billed as Dorothy Ruth Morris.

(Morris reminisces about her short-subjects experience in the Turner Classic Movies documentary Added Attractions: The Hollywood Shorts Story, first broadcast in 2002.)

In the late 1950s, she made guest appearances on television series such as The Untouchables, The Donna Reed Show, Rawhide, Casey Jones, and Wagon Train.

Her last television appearance was in a 1971 episode of Marcus Welby, M.D.. Morris was married to Marvin Moofie, a math teacher at Los Angeles Unified School District.
