Sammo

Continuity mistake: Vera is looking outside the window before Lombard plays the piano; she has one hand against the glass, but the arms are low down her body in the next shot. (00:36:10)

Sammo ★

Continuity mistake: When the Judge sets up his reveal that Mr. Owens must be one of the guests, look at the shot of the whole room; Blore is leaning with both one arm and both hands on the armchair, and Dr. Armstrong is holding the knife in one hand. This is the same way everyone will look in the last shot of the scene too. Any other dramatic shot in between, with Blore initially with both hands on the table, or Dr. Armstrong holding the knife in two hands, and even the butler counting with the aid of his fingers instead of keeping the fists clenched, is moot. (00:35:00)

Sammo ★

Continuity mistake: After the General's murder, Thomas Rogers calls the doctor and announces that there's another figurine missing. In close-up, Richard Haydn's hand is on his chest, while he has both down his sides in the shots of the whole room. (00:34:30)

Sammo ★

Continuity mistake: Blore and Lombard are watching outside during the storm, with everyone inside the house but general Mandrake. From the outside looking in, Lombard is only partially in the window, and Blore is turned sideways. Indoor shot; Blore is facing the window frontally, and Lombard is all the way visible, perhaps just a part of his foot would be obscured by the curtains. (00:32:25)

Sammo ★

Revealing mistake: Rain is pouring on the windows, but when Lombard comes back with the bad news about the General, he's in pristine condition. (00:33:50)

Sammo ★

Continuity mistake: When Vera reports the General's ominous phrase "He said the boat will never come", she's standing by the window - the leftmost window of the dining room, as visible later - but she wasn't there a moment before, when Quincannon and Armstrong were talking. (00:33:30)

Sammo ★

Continuity mistake: Lombard on the cliff says "Mr Owen's hand is plain to see"; at the cut, the clouds in background are different, and the hat on Barry Fitzgerald's head adjusted itself - it was about to fly off in the previous shot. (00:32:10)

Sammo ★

Continuity mistake: The men are looking down the cliff in search for possible hiding places. Blore asks the doctor if he OD'd the maid; he does it without a hand on his hat (he lowered earlier in the first shot) and then with the hand on it in the next shot. (00:31:50)

Sammo ★

Continuity mistake: Vera approaches the General on the beach. He calls her "Juliet", mistaking her for his dead wife; during the close-up on June Duprez, the lighting is different and the foulard is windblown harder. (00:31:00)

Sammo ★

Continuity mistake: Miss Emily Brent points her binoculars at the beach in the same shot when the men decide to start searching the island. She witnesses a brief exchange between Vera and the General, then follows Vera's movements who are in strict continuity. Merely a minute has passed, and the guys already are on the beach (which already can be quite a feat) discussing how their search was fruitless. They haven't searched a thing in so little time. (00:30:25)

Sammo ★

Continuity mistake: Vera reaches on the beach Gen. Sir John Mandrake. When she exclaims "Sir John!" after he asked her (or rather, his dead wife) why does she love 'him', the sky is overcast and the shadows change radically in the next shot. (00:30:50)

Sammo ★

Continuity mistake: In the scene with the various characters (Blore, the doctor, the judge) spying on each other, the keyholes the camera looks through are always perfectly lit, with none of the shadows the characters cast on the lock in the other views. (00:27:25)

Sammo ★

Continuity mistake: Blore asks Lombard from the other side of the door "You mean you haven't any weapon?", hands off the handle. Hand on the handle in the shot that follows. (00:27:30)

Sammo ★

Other mistake: When the judge and everyone else observe and comment the fact that two figurines are broken, nobody has a clean line of sight to them; they talk about what the movie spectator is seeing. (00:24:30)

Sammo ★

Continuity mistake: When the doctor announces that "Mrs. Rogers died in her sleep", the Judge 's hand with the pipe goes from in front of the chest to down his side. (00:25:00)

Sammo ★

Stupidity: The doctor smells the poison in the glass, but to be perfectly sure, decides also to taste it. Why not, what could possibly go wrong?

Sammo ★

Continuity mistake: After his confession, the prince plays the piano no-stop when he's not in frame, but the glass awaits him closer on the sheets than it originally was when he picks it up to toast yet again. (00:19:30)

Sammo ★

Continuity mistake: The prince tells the sad story of his driving license revoked - with two people dying as collateral damage. Judge Francis J. Quincannon stands and then leans over the back of the chair; his arms switch position, crossing with the right in front, then the left in front. (00:19:50)

Sammo ★

Continuity mistake: When Mrs. Rogers yells at her husband, behind her in close-up you can see on the portion of floor in frame the silverware she was carrying and that is by her; she moved forward quite a bit. (00:16:20)

Sammo ★

Continuity mistake: At the end of the macabre performance at the piano by Mischa Auer, he grabs his drink and raises the glass - which is lowered at the instantaneous cut to a new angle. (00:13:30)
