Clue (1985)

Continuity mistake: When everyone is in the Library, you can see the matches in a cup on the left of the fireplace. When Professor Plum says, "Wait a minute, suppose that one of us is the murderer," you can also see that the matches are in a "V" shape. When Wadsworth walks towards them to pull the matches out, most of them are all leaning to the left side of the cup. As the movie goes on, when the cop gets locked up in the Library for the second time, the same amount of matches are in the holding cup as if Wadsworth did not pull them out and they are in a straight line. (Third time code 1:02:40). (00:44:25 - 00:45:05)

Wadsworth: The game's up, Scarlet. There are no more bullets left in that gun.
Miss Scarlet: Oh come on, you don't think I'm going to fall for that old trick.
Wadsworth: It's not a trick. There was one shot at Mr. Boddy in the study, two at the chandelier, two at the lounge door, and one at the singing telegram.
Miss Scarlet: That's not six.
Wadsworth: One plus two plus two plus one.
Miss Scarlet: Uh-uh. There was only one shot that got the chandelier, so that's one plus two plus ONE plus one.
Wadsworth: Even if you were right, that would be one plus one plus two plus one, not one plus two plus one plus one.
Miss Scarlet: Okay, fine. One plus two plus one...SHUT UP! Point is, there's one bullet left in this gun, and guess who's going to get it!

Trivia: The producer's first choice for the role of Ms. Scarlett was Carrie Fisher, but she was unable to sign onto the film because she'd recently admitted herself to a rehab facility to battle drug addiction.

Question: Are Colonel Mustard's parents dead or not? During the blackmail discussion scene in the study, Mustard says he lost his mummy and daddy in the war. Later, Mustard says Mr. Boddy threatened to send the pictures of him and Yvette in Flagrante Delicto to his parents.
