'The Black Windmill' (1974) – Don Siegel.
In my youth I read a rather disparaging critique of Don Siegel's 'The Black Windmill', and while said individual manifestly has every right to express his low opinion, I, conversely, maintain a great appreciation of this exciting Michael Caine thriller. With maestro Siegel at the helm, the film-making is of an expectedly high standard, he has assembled an no less qualitative cast, and the sinister spy vs spy shenanigans are electrified by another exemplary Roy Budd score. Watching an inscrutable, credibly steely Caine forcefully extricate himself from these increasingly malign machinations, and rescue his beloved son still provides a generosity of knockabout thrills. One always has the palpable sense that his son is in gravest danger, generating genuine empathy, humanizing Caine's flinty, necessarily brutalist avenger. Siegel's fabulous 70s action/thriller looks resplendent on HD, as does Donald Pleasence's magnificently twitchy performance.
