In 1965, Caine created the role of Harry Palmer in the Ipcress File. It was good enough to spawn two follow-ups: Funeral in Berlin and the Billion Dollar Brain. By 1974, the movie-going public was used to seeing him in the role of a secret agent. Here he gets in trouble, and although you know that by the end of the film he will emerge victorious, or will he? I'm not telling. But the excruciating fun is in trying to figure our what will happen next. Filmed in Europe, Black Windmill" is directed by Don Siegel. Clint Eastwood credits Don for his success as a director, and, of course, Siegel also directed some of Clint's best movies. The pacing is even throughout and builds to a suspenseful climax. Let it not be overlooked that Donald Pleasence in a supporting role is at his usual best. The human chameleon that adapts beautifully to whatever role is given him. John Vernon is especially menacing. To me, seeing old movies a second or third time is like visiting with old friends. Everybody has their own "Casablanca" and "Shawshank Redemption." If you haven't seen this one yet, please do. It will become one of your "old friends" which I'm sure you will visit again and again.
