« But Michael Caine as the title character is no pale imitation of other iconic law-abiding men. He's quietly mad as hell and raises the level of the film with his grave intelligence and contained ferocity. The film, directed by Daniel Barber, works best as a character study set in a gritty, realistic atmosphere. »
« L'ensemble bénéficie en outre de l'exécution relativement sobre du nouveau venu Daniel Barber qui, y allant d'une mise en scène au point, ménage ses effets et soutient habilement la tension. Si bien que l'invraisemblance du dénouement ne se manifeste qu'après coup. »
« Harry Brown peut par ailleurs compter sur une mise en scène étonnamment maîtrisée de Daniel Barber, qui signe un premier long métrage noir, intense et troublant. »
« At 77 years of age, Caine has lost none of his ability to hold a stage. The fact the film was shot in the graffitied, garbage-strewn remains of his own old neighbourhood seems to have put an extra kick in his step. He brings both dignity and purpose to an enterprise that would otherwise deserve accusations of exploitation. »
