Chicago Reader review:
Joseph Losey's coldly funny puzzle movie (1967), about the erotic entanglements of Oxford as superbly entangled by scenarist Harold Pinter. Dirk Bogarde's crumbling don is the sharpest of the many similar performances he has given, and Stanley Baker is superbly chunky as Bogarde's rival for a young Austrian student (Jacqueline Sassard). With Vivien Merchant, Michael York, Delphine Seyrig, and Alexander Knox.
Here (and above) is the trailer.
