Character mistake: Charlie tells Thedy that the hair ribbon embroidered with her name cost 65 cents, "five cents a letter." But her name is Thedy Sue Hill, which is only 12 letters - or 60 cents worth. (And no, the extra is not due to a sales tax, which in 1962 would have been two cents, tops, and didn't even exist yet in many states.). (00:12:00)
Suggested correction: This was not an error. Charlie is a bumpkin. He was ripped off due to his lack of intelligence.
Factual error: After emptying the safe, Gerald shoots the night watchman through a glass door. But somehow, the glass never breaks. (00:02:05)
Continuity mistake: Gerald holds the wine glass upside down, taping the broken stem back on. But when the shot cuts, he's instantly holding it upright instead. (00:14:30)
Revealing mistake: Gerald hides what are supposed to be thousand-dollar bills inside Emmy's magazines. But the money he's handling all carries George Washington's portrait. It's one-dollar bills. (00:30:00)
Continuity mistake: When Clemens is stopped by the police, the shoulder of his raincoat is clean, then has wet leaves all over it, then is perfectly clean again. (00:02:30)
Continuity mistake: During his questioning inside the house, Clemens' hair goes back and forth from falling over his forehead to brushed back several times between takes. (00:05:00)
Water's Edge - S3-E3
Factual error: Pete Taylor's corpse is a bare skeleton after just two years in the sea-shack's attic, though it shouldn't be. There should at least be traces of hair and clothing surrounding the bones. (00:40:00)
Water's Edge - S3-E3
Revealing mistake: The murder victim's skeleton, which Rusty finds in the attic, has a clear cut all the way around its skull. It also has metal pins holding together what turns out to be rubber bones: one of the ribs wobbles up and down when Rusty brushes against it with the cash box. (00:42:00)
Continuity mistake: At the end, Stella rips open the female impersonator's blouse, exposing his hairy chest. But in the following shots, the blouse is once again buttoned up tight. (00:49:00)
Continuity mistake: In the dining room, Mary places the telephone on the kitchen counter by reaching through the double doors over the bar. The doors, which she pulls shut, bounce back open slightly on their own. Mary then commits suicide. No one else has been there, but when Agatha returns to discover the body, the bar doors are tightly shut again. (00:35:10)
