French New Wave director Claude Chabrol made a 10-minute version of M for the French television program Cine-Parade that aired in 1982. It covered the basic motifs down to shot selections. Chabrol appears in a short interview segment discussing Lang's films and techniques.

There are classroom audiotapes from the New School University with M editor Paul Falkenberg discussing the film and its history in 1976 & 1977. While an unbelievably impressive find, he didn't provide much insight that was worth learning other than the bit of trivia that Lorre doesn't do the whistling. Lang's wife did. This can be skipped.

A Physical History of M is the best item of the bonus materials as it shows the different ways M has appeared over the years. When it was re-released in theatres a new credit sequence was created and audio was added to the intentionally silent sequences. This documentary shows a comparison. It also shows how Lorre's finals scenes in M were used in the anti-Semite propaganda film The Eternal Jew(1940).

This documentary also shows how M was altered and in some instances butchered in France. When Beckert first appears as a shadow on the wanted poster, the scene was reshot so the poster would be in French. During the film's climax, when Beckert talks about his crimes in front of the criminals' kangaroo court, Lorre reshot his scenes speaking his lines in French. Those scenes were inserted into the film with the original footage that was dubbed.

The biggest travesty is that meaning of the picture was changed by the alteration of the final scene. Lang showed grieving mothers in court, issuing a warning to themselves and the audience. This was changed to a scene of children playing carefree as if to say that now the trouble is over. Whoever made this decision missed the entire point of the film. The film was no longer a warning for parents to better protect their children, but became a simple thriller where murder was part of the entertainment, which was something Lang was against.

This two-disc set is a must-have for any serious film library.
