The McKenzie Break

Rare reversal of the PoW camp formula, with Germans the potential escapees from a Scottish internment. Keith and Hendry do ideological battle with fanatical Nazi Griem, who is willing to sacrifice half his less politicised men to cover his planned breakout. Elaborated with unusual care for authenticity, it's tautly handled by Johnson (better known for abrasive telemovies), and adapted from Sidney Shelley's novel by William Norton (father of Convoy adaptor and More American Graffiti director BWL Norton).
