I love watching his films and think many deserve nomination into the Canon. There's already a thread for Holy Mountain, but I prefer El Topo b/w Danza De La Realidad as they tell the same story but from very different perspectives.
I admit that Danza just barely beats out Lego Movie for my favorite movie of all time (a spot once held by Babe and The Straight Story), so this could be an indulgence pick, but Jodorowski's movies feel essential to a discussion on the power of film.
