This studied black-and-white noir (1998) about an earnest man with a dangerous hobby seems ungimmicky only because elements such as the 16-millimeter cinematography mute the cliches, including the achronological story structure. Questioned by someone who may be a detective or a psychologist, Bill recalls his experiences following strangers on the street, one of whom becomes his doppelganger in a relationship as devoid of intrigue as the plot twist that resolves the lazy philosophical story. Written and directed by Christopher Nolan (Memento); with Jeremy Theobald, Alex Haw, and Lucy Russell. R, 70 min.
