... and not his best movie by far : very talkative, dull casting, no rhythm, only a few good scenes in an hour movie that lacks a real script. Cy Enfield would do a much lot better two years later with "The Underworld Story" and "The Sound Of Fury", in 1957 with "Hell Drivers" and of course in 1964 with "Zulu", strong movies with real casting. But forget this dull "Argyles Secrets".
