A truly inspirational real-life war hero(ine), Odette Sanson's story is so dramatic and fascinating that it's eventual translation to the cinema screen is as inevitable as night following day. Tastefully done yet still powerful – with strong performances from Anna Neagle, Trevor Howard, Marcus Goring and Peter Ustinov – the film is a good, solid bio-pic all-round.

During WWII, mother of three Odette Sanson (Anna Neagle) offers to work for British Intelligence. She is given a new identity and back-story, and dispatched to France where she comes under the command of top Allied spy Peter Churchill (Trevor Howard). Churchill has within his jurisdiction a small spy network working furtively and endlessly against the German war machine, among them the impetuous and courageous Alex Rabinovich (Peter Ustinov). Odette proves her own worth smuggling some vital documents out of Marseille, and is soon hailed as one of the most invaluable members of the team. Later she is captured and tortured by the Gestapo, but stubbornly refuses to yield any information, simultaneously surprising and infuriating her Nazi captors. After various trials and tribulations, she returns to England a bona fide war hero(ine) when the fighting ends in 1945.

After a stodgy and rather clumsily handled opening, Odette picks up pace, interest and drama as it gets going. Neagle handles the title role pretty well, conveying the stubborn pride and inner courage of the character most effectively; Howard too is solid (if a little underused) as her superior and eventual lover. The film is crisply shot, sometimes on the studio backlot but quite often on authentic continental locations, and generates an evocative sense of atmosphere in its dangerous world of wartime skulduggery and military intrigue. The torture sequences manage to be extremely distressing without showing everything in nauseating detail (a trick modern film-makers would do well to learn from), and a good level of tension is sustained pretty much throughout as Odette carries out her clandestine deceptions in this riskiest of times and places. All-in-all, Odette is a good film in the old-fashioned mould.
