Romulus Ledbetter (Samuel L. Jackson) is a schizophrenic homeless man who lives in a cave in a New York City park and believes that his nemesis is trying to control the world by projecting mind-control beams from the Chrysler Building. Based on the novel by George Dawes Green, "The Caveman's Valentine" is a unique trip into the disturbed but still highly intelligent mind of a character only Samuel L. Jackson could pull off. Director Kasi Lemmons, who previously directed Jackson in "Eve's Bayou," takes us inside Romulus' mind using spectacular and jarring special effects, yet never letting the viewer forget the simple, human drama at the heart of the film.
