Appearing in bit parts in several of the studio's more successful films, Morris was signed to a
Metro-Goldwyn-Mayer contract in 1941. For one of her early film roles, ''
Cry 'Havoc' (1943), she affected a British accent. 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. Morris' role was Mary Arena; the girlfriend of
Van Johnson's character. The highlight of her career, however, came in 1945 when she starred as the doomed Ingeborg Jensen in
Our Vines Have Tender Grapes. Other screen roles included
Someone to Remember (1943),
Pilot No. 5 (1943),
Rationing (1944) and
None Shall Escape (1944). Morris is often remembered for her featured appearances in MGM short subjects. She appeared in several of the studio's short films including the
Pete Smith Specialties,
The Passing Parade, and
Crime Does Not Pay series. 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.) == Later career ==
