Context: When Pasternak stopped producing Durbin's pictures, and she outgrew her screen persona and pursued more dramatic roles, the studio signed 13-year-old Gloria Jean for her own series of Pasternak musicals from 1939; she went on to star with Bing Crosby, W. C. Fields, and Donald O'Connor. A popular Universal film of the late 1930s was Destry Rides Again (1939), starring James Stewart as Destry and Marlene Dietrich in her comeback role after leaving Paramount Studios.
