Just recalled another one —”92 in the Shade” with Warren Oates, Peter Fonda, and Burgess Meradith. That one’s beyond cult — it’s a hidden gem. Harry Dean was great as usual. So human.
He was in at least 2 other movies with Warren Oates, Two-Lane Blacktop (minor role) and Cockfighter (supporting role) both by director Monte Hellman.
