This is a hard one but ...
Shawshank Redemption
Dune.
The good the bad and the ugly.
Ratatouille. ( the animated movie from Pixar ) it prolly hit me more as i work as a chef and the details of the movie is just so good.
Olsen Banden ( Danish movie *serie* ) i think this series of movies are close to many danes hearts and includes 14 full movies, the first came out in 1968 the last in 1998 with largely the same actors and later came a few animated movies .... we do not talk about the last movie and whatever came after that.
