The most respected name in home video, Criterion, has turned its attention to Fritz Lang's The Testament of Dr. Mabuse. This two-disc set offers a standard full-frame transfer that preserves he original theatrical aspect ratio of the film. The German soundtrack is rendered in Dolby Digital Mono. Supplemental materials include a commentary track by author David Kalat; footage from a 1964 interview with Lang; comparisons of the German, French, and English versions of the film; production design drawings; the complete French version of the film; and an essay on the great director by Tom Gunning. This is, as expected, a superb title from Criterion.
