My father has been reading a biography on Peter Lorre, so this past weekend we watched one of his first films, M. With only twelve lines of dialog, Lorre does a great job of acting and looking like a crazed child murderer. I agree with the many film critics who say that "M is a cinematic masterpiece of visual drama" - the cinematography is great. This movie was made 75 years ago and is also interesting to see for its history - it was banned in Germany shortly after it premiered, and Fritz Lang and Peter Lorre, both Jews, soon fled the country.
Make sure to watch the best movies first, or you may not have a chance to watch them at all - and M is one of the best.
