'61; two popped into mind before I even finished your thread: 1. "Tremors" with Kevin Bacon and Fred Ward, set in the Nevada desert, it's got fast digging under ground monsters they named Graboids (I've worked in the Nevada desert), the interplay among the characters is excellent and the "light science fiction-horror" theme is great. There are a lot of intangibles that come together that make this movie for me but especially the interplay between Bacon and Ward. I think this movie has achieved cult status.
2. "Streets of Fire", sub-titled "A Rock & Roll Fable", stars Michael Pare', William Dafoe, Amy Madigan, and Rick Moranis. The soundtrack by Ry Cooder is excellent. Set in a large city in the 1950's (maybe Chicago?), it has cowboy names, ie Tom Cody and Ellen Aim, cowboy rifles (M94 Winchesters), a motorcycle gang complete with Harley's, and a chopped 1950 candy apple red Mercury convertible. I believe this was a british "take" on the way American society works-- at least in a movie, and in the 50's-- it's great.
I think the Lethal Weapon movie series also fits into this category. Cheers. Craig
