What can you say about the movie that taught you what movies were? The first time I saw Kane I discovered the existence of the director; the next dozen or so times taught me what he did—with lights and camera angles, cutting and composition, texture and rhythm. Kane (1941) is no longer my favorite Orson Welles film (I’d take Ambersons, Falstaff, or Touch of Evil), but it is still the best place I know of to start thinking about Welles—or for that matter about movies in general.
