The British actor Damian Lewis gives the performance of his career in this involving, compassionate picture by US indie writer-director Lodge Kerrigan. It is a riveting portrait of a man on the edge of an abyss: an abyss of poverty, of insanity and despair - but, importantly, he is not quite over the edge yet. Kerrigan's camera is in Keane's haunted face for almost every minute of the movie's running time, searching out every flicker of unease and tortured hope. As an actor, Damian Lewis has been stretched as never before, and gives an outstanding performance.

An intense, claustrophobic study of a man haunted by the kidnapping of his daughter, Keane is a grimly compelling showcase for the exceptional British actor Damian Lewis. Under Lodge Kerrigan's assured direction, Lewis gives a painfully raw performance in the title role of this ultra-realistic indie character study. Screened at the 2005 Cannes Film Festival Director's Fortnight, Keane is an emotionally harrowing film. For the more adventurous viewer seeking provocative fare, Kerrigan's third film confirms that he's a filmmaker of acute sensitivity and psychological nuance.
