This was actually released on blu-ray last week, but it's a far better selection than anything that came out today. One of the all time great film noirs with the woman who practically created the femme fatale at the center of it. Billy Wilder wrote and directed this story of a man (Fred MacMurray) who falls prey to the wiles of a dangerous woman (the incomparable Barbara Stanwyck) who gets him to conspire to murder her husband. Everyone knows this story by now (there's also a really good remake of this in 1981's Body Heat), but this is the original and every inch of it is cool, cunning perfection. You owe it to yourself to check it out.
