There are hard men, and there is Stanley Baker in 'Yesterday's Enemy'.
Directed by the criminally under-rated Val Guest (is there no genre the man couldn't handle?) from Peter Newman's intelligent, thoughtful - and brutal - script, Yesterday's Enemy is a masterclass in every respect.
Baker and Leo McKern were rarely better than here, and are ably supported by the likes of Guy Rolfe and Gordon Jackson but it's the script, and Guest's subtle, claustrophobic direction which elevates this to the very peak of British war movies. Not so much shades of grey, as a blanket fuzz of the same grim shade, there's no winners, only losers here, but (save, perhaps, for the final words from the British radio) there's no judgement either.
