Streetwise is a 1984 documentary film by director Martin Bell.
According to Mark's accompanying, 1988 book, also named Streetwise, McCall and Mark travelled to Seattle specifically to reveal that even in a town that billed itself as America's most liveable city, there still existed rampant homelessness and desperation. After making connections with several homeless children during the writing of the article, Mark convinced Bell that the children were worthy of his making a documentary based on their lives. McCall and Mark were also instrumental in making the film. Streetwise follows the lives of several homeless teenagers, although it focuses most on 14-year-old Erin Blackwell, a child prostitute who goes by the name of Tiny. Much of the time, Tiny stays at the home of her alcoholic mother, Pat, who seems unfazed by her daughter's prostitution, calling it a "phase".
