This starts a train of thought. I caught roughly the last half of the movie last night, including the cliff-jumping scene, and was reminded how unusual the movie is for telling a Western story with a late-1960s sensibility. This goes well beyond the use of a contemporary Burt Bacharach score, to include Goldman's writing style, and the performances by Redford and Newman. I almost imagine the two actors on day one of the shoot giving performances that fit the usual "Western acting" mold, and George Roy Hill responding, "No, no, I want you to inflect the dialogue like it's happening in 1969." And then I thought, wow, that was pretty revolutionary. And then I thought, well, no, it has a definite predecessor: Cat Ballou. And then I wondered if Butch Cassidy, as we know it, would have existed had there been no Cat Ballou.
