Baxter Grant (Van Johnson) an American military doctor in West Berlin, deserts and goes on the run from the Military Police when faced with false drug trafficking and murder charges. He takes shelter in the apartment his wife rented not realising it’s been sublet – so he finds himself hold up with cabaret singer Lilli Hoffman (Hildegarde Knef) who he manages to persuade to help prove his innocence. He is being hunted down by the military, his wife (Katharine Kath) is the sole person to be able to help but he suspects her of black market involvement while his estranged son (a soldier) wants to hang him out to dry … Directed by the estimable Muriel Box this is of interest principally as a Cold War tale but it’s hamstrung by the lack of location filming (it was shot in Shepperton and the only exteriors look like North Kensington). Essentially it’s a chase movie that mostly takes place in the apartment. Knef comes off best here and while she’s no Dietrich she’s no slouch either in her nightclub singer role with that gravelly voice coming into its own. There’s a nice supporting performance by Albert Lieven as Carl, her lawyer. Adapted from Bruce Birch’s book and Ian Main’s play by Jack Andrews.
