Foxhole in Cairo

Foxhole in Cairo is a 1960 British war film directed by John Llewellyn Moxey and based on a novel by Leonard Mosley itself based upon the reallife Operation Salaam. It starred James Robertson Justice, Adrian Hoven, Fenella Fielding and Henry Oscar. Future star Michael Caine makes a brief appearance as a German soldier, in one of his earlier screen roles.

A 1961 New York Times review described the film as a routine Britishmade espionage yarn calling the plot slack and predictable, while praising the professional performance of James Robertson Justice.
