Robert Sidomak's The Killers (1946) starring Burt Lancaster and Ava Gardner is classic film noir. The story is based on a Ernest Hemingway short story, but it's only the opening part. The rest is a bout a heist that goes wrong and a femme fatale that essentially destroys the Swede (played by Lancaster). It is has all the classic elements of a film noir with underworld locations, double crosses, and murders. I have found that there is a 1964 version that had Ronald Reagan in it, I was under the impression that he was in this earlier version, but I will watch the 1964 version soon as well. Apparently the story is significantly different.
