Francis Ford Coppola is good at many things, but mainly at these two:
1. Making films
2. Doing a Marlon Brando impersonation
Also, Coppola is one of the most intelligent people you will ever have the pleasure to hear. This short excerpt (0:58 till 2:33) from an Apocalypse Now interview says more about art than any lecture or thesis. Basically, the whole point is laid bare before you.
