This Ealing film about the exploits of Yugoslav partisans fighting the occupying Nazis provides 90minutes or so of harmless entertainment. Filmed, I believe in Wales, where the mountains are not that high it's most notable feature for me is that it is Stanley Baker's first film appearance. 16 years old at the time he plays a schoolboy who aspires to be a guerrilla along with several of his schoolmates. He has a decent amount of screen time and lines. The plot is pretty much standard for this type of film; two brothers one a fighter, the other an apparent (although not to the audience) collaborator.There is sabotage, general mayhem and executions which fit nicely and keep the film moving along apace.Certainly worth watching if you get a chance to see it.
