Night Train to Munich (1940)

Reuniting The Lady Vanishes (1938) team of Lockwood and writers Frank Launder and Sidney Gilliat, this thriller was a hit in the USA, where Gordon Wellesley’s original story was nominated for an Oscar. The scenes of Lockwood in a concentration camp were fairly unique, as the Ministry of Information feared reprisals on British POWs if films exaggerated their treatment. The top-billed Lockwood cemented her popularity with the UK public as the seemingly demure but feisty heroine.
