Lisa Turtle (Lark Voorhies) drinks a mango tonic with a kiwi twist. The beverage is pink despite the fact that none of its ingredients are.
When the detective is going through his questioning, Mrs. Bankhead's necklace appears in one shot then disappears in the next, before the lights goes out, and it is reported "stolen".
Lisa pushes Mr. Jameson out of the way well before the ax begins to fall.
Mr Jameson warns the guests that events (the ax falling, the jewelry being stolen) were not planned and that everyone had better leave while they can. What if everyone had left and no one figured out that these events were in fact part of the game? They would have had to refund everybody's money.
Before he is "killed", Detective Piccadilly says that "the real murder is", instead of "the real murderer."
