About two-thirds into the film, an unconscious man is discovered lying fully clothed on a bed. The first shot of the man shows only his left hand, palm down, near the left side of the bed. This implies that he is lying on his back. But moments later, in a wider shot, the man is shown lying face down.
In the 1950s set part of the film, characters are drinking champagne from flutes. At this time the standard champagne glass was a saucer - shaped one.
