I couldn't resist a capture of Jane Fonda dressed up as Hildy/Rosalind Russell:

That's from The Electric Horseman. I have been watching a lot of 70s cinema for a current project and am starting to think I prefer the popularizers over the unreconstructed New American Cinema auteurs. In any case, I'm curious in thinking about the relation between auteur production, genre production, and the interstices.
