This is a very thought-provoking movie. Another one I would recommend that is more obscure is “Wild in the Streets”. I’m certain that Bill Clinton got a ton of inspiration from this movie (in fact, this movie actually suggested stealing FBI folders on political leaders to use as leverage, which is exactly what the Clintons did!).
I have seen both. I thought Andy did his most “acting” in Faces. As far as WITS, it’s Fourteen or Fight! It was a fun movie and I’d watch it again if it comes on TCM. As far as surreal movies Videodrome and Mr. Frost are memorable.
