Of all his films, the best IMHO was Aguirre, Wrath of God. A movie that explores raw power. I think this was his top achievement in film.
Fitzcarraldo is also up there, and cool... actually (in the movie and for real) moving a LARGE steamship to the top of a mountain in, I think, Peru?... and dropping it on the other side, as it careens thru a river, with Klaus Kinska its “owner” and passenger.
Fitzcarraldo is a great film.
Stroszek was very good, too. Although some film critics have portrayed it as an indictment of the American dream, it is anything but, IMO. It is a study of the consequences of self-destructive behavior.
