TCM (Turner Classic Movie) channel has been mentioned a couple of times. I saw a really great one two nights ago, "Laura" from 1944. Great acting, story with a real twist that worked, I highly recommend if you haven't seen it. Directed by Otto Preminger and for his part Clifton Webb won an Oscar for best supporting, you may remember him from Cheaper by the Dozen or John Phillip Sousa story "Stars & Stripes Forever.
Dana Andrews, Vincent Price, Gene Tierney and Clifton Webb
