Eurotrash host Antoine De Caunes is not the first person you'd associate with a costume drama charting Napoleon's final years, but the English-mangling presenter-turned-director makes a fair fist of this handsome period piece. The problems lie more with the script, which renders a fascinating puzzle -" did Bonaparte really die in exile on St Helena? -" sluggish and turgid.
Unlike The Emperor's New Clothes, which imagined Ian Holm's despot back in France, Monsieur N confines its hero (Philippe Torreton) to his island prison, ekeing out his days under the watchful eye of Richard E Grant's twitchy governor. But is Boney beaten, or is he quietly plotting his escape? Screenwriter Rene Manzor employs a Citizen Kane-style framing device to explore the various conspiracy theories -" was Napoleon poisoned by the British? Was his butler buried in his place? -" but his stubborn refusal to resolve the mystery reeks of cop-out. Not tonight, Josephine.
