"Rotten Tomatoes asks some of the biggest names in Hollywood: Name Your Five Favorite Films."

Links to the various lists are well-organized in this Metafilter post.

Which name did you impulsively click on first? I clicked on Werner Herzog, who likes "Freaks," "Intolerance," "Rashomon," "Nosferatu," and a movie I don't remember ever noticing before, "Where is the Friend's Home."

About "Rashomon" — which I once wrote an article about — he said:

It is probably the only film that I've ever seen which has something like a perfect balance, which does not occur in filmmaking very often. You sense it sometimes in great music, but I haven't experienced it in cinema, and it's mind boggling. I don't know how [Akira] Kurosawa did it. It's still a mystery to me. That's greatness.
