Harold and Maude and Wes
I just saw Harold and Maude for the first time, and it is a great movie! It seemed like a Wes Anderson film, but since it predates anything Wes Anderson has done, I figured it must have been an influence for him. Then, searching IMDB, I found that Bud Cort of H&M has a part in Wes Anderson's next film. I am sure this is not a coincidence.
