Joseph Campbell and the Power of Myth
1988 · Catherine Tatge · ★★
Six conversations between Bill Moyers and Joseph Campbell, filmed over the last two summers of Campbell's life and broadcast eight months after he died. This is where the hero's journey comes from, and five of the six were shot at Skywalker Ranch, which tells you what Lucas reckoned he owed it.
