If you want to see a hilarious documentation about Mozart's (aka Wolfgang Romatz Edler von Sauschwanz aka Franz v. Nasenblut) life, go and watch
Der Wadenmesser. Mozart had an incredibly strange life, and
Kurt Palm presents it in an extremly funny but still well-researched way, with lots of more or less useless facts, in a style similar to "Sendung ohne Namen", but way more relaxed. The movie also contains its cruel scenes, like an ox is being slaughtered, or a real person having a real blood-letting! And if you really watch this movie, be sure to memorize the riddle in the beginning, because you will have to wait for the answer for several thousand seconds, and they won't tell you the riddle again in the end, only the answer...
