Perhaps the most intriguing fact about this clever, touching, and well-directed independent feature is that the script was written by the late Endre Bohem in 1935 and revised by his son Leslie only a few years ago--a form of generational continuity reflected in one of the delayed revelations of the plot as well. The story--set in the present, though one can imagine it set during the Depression--concerns the fate of a single $20 bill that's dropped on a city street, picked up, spent, given away, lost, and pursued by many people for multiple reasons, always gaining new significance with each new setting. Most of the resulting miniplots are self-contained, but the script also gracefully brings back characters, making a roundelay exercise like the recent Chain of Desire look fairly crude by comparison. Documentary filmmaker Keva Rosenfeld has switched to fiction with a great deal of craft and assurance, never allowing the large number of characters to seem top-heavy or confusing. The able cast includes Linda Hunt, Elisabeth Shue, Christopher Lloyd, Steve Buscemi, Brendan Fraser, Gladys Knight, Melora Walters, and Kamal Holloway.
