Much better than camp but a little too lurid for art, Charles Vidor’s 1946 film is one of the high points of postwar romanticism, snide and sentimental at the same time. George Macready, slimy owner of a Buenos Aires casino, hires out-of-luck American Glenn Ford to tend the crap tables, unaware (or is he?) that Ford was once in love with his wife, Rita Hayworth. Hayworth’s rendition of “Put the Blame on Mame” has been known to provoke impure thoughts.
