50FilmChallenge
Since 2007 I make a 50 film challenge (on LJ).
The challenge I set myself is to watch 50 new films each each year. (I keep track of re-watches as well but I don’t count them for the challenge)

1001 movies you must see before you die
I try to watch all movies of the 1001 movie list

Filmkanon der Bundeszentrale für politische Bildung
I try to watch every film on the Filmkanon.
