An ankle bracelet. Statue of a bird. Femme fatales. Blackmail. Sex. Corrupt cops and not-by-the-book private detectives. And guns, always guns. Unless, of course, it’s a knife. These are just some of the things you can see in film noir, French for “black film.” The popular movies from the ‘40s and ‘50s are this summer’s guilty pleasure showing at the Louisville Palace. I look forward to their film series every year and have to say this selection is a killer (insert collective groan here). Marquee movies still to come on Fridays and Saturdays through August are “The Killers,” “The Postman Always Rings Twice,” “Lady from Shanghai,” “Key Largo,” “Asphalt Jungle,” Sunset Boulevard” and “Touch of Evil.” Raincoats, fedoras and the proper way to say “baby” optional.
