Full of adorable little models and British actors as comic-book Germans clicking their heels and strong-arming women and children, their victims played by slavic types like Niall MacGinnis when he still had a full head of hair, Finlay Currie, Michael Wilding and Tom Walls (the latter grumbling at his son that "Guerrillas were different in my day!").

Sunny Wales masqueraded as Central Europe, which presumably explains the presence of a fifteen year-old Stanley Baker, one of the few cast members who doesn't have an English accent.
