Character mistake: During the conversation in the study about who is blackmailing who, Mrs. White mentions two of her five husbands: An illusionist who disappeared and never reappeared and a nuclear physicist who was found dead at home. During the last ending, Mrs. White says "So this has nothing to do with the disappearance of my nuclear physicist husband or Colonel Mustard's work on the new top secret fusion bomb?". However, during the conversation in the study, Mrs. White says her illusionist husband had disappeared and her nuclear physicist husband was found dead at home. So the correct term would be "So this has nothing to do with the disappearance of my ILLUSIONIST husband or Colonel Mustard's work on the new top secret fusion bomb?". (00:21:05 - 01:27:35)
Suggested correction: Ms. White's nuclear physicist husband disappeared too, so the line is right.
