On the Loose was produced by the Filmakers Organization, consisting of producer Collier Young and director Ida Lupino (Mrs. Young at the time). Joan Evans stars as Jill Bradley, a teenager with an undeserved reputation as a "bad girl." No one -- not even her parents Melvyn Douglas and Lynn Bari -- will give Jill the benefit of the doubt. Only when the girl attempts suicide are her selfish parents awakened to her plight. Intriguingly, On the Loose was scripted by the husband-and-wife team of Dale Eunson and Katherine Albert, who happened to be the real-life parents of star Joan Evans. Though most Filmakers productions were directed by Ida Lupino, On the Loose was helmed by screenwriter Charles Lederer.
