Continuity mistake: During the introductions, Ilona Bergen exclaims; "How awesomely marvellous" with Blore casting on the wall by her a Hitchcockian-esque shadow with his profile. The shadow comes from nowhere, since the previous shot of the room lacked that and the other shadows (like the vase's) are unchanged. (00:06:25)

Continuity mistake: Mr. Owen is playing billiards on his own when the last survivor joins them; at the very end, it turns out that the tray with the Indian figurines is on the pool table too too, but it was not there and nobody could have added it. (01:24:50 - 01:29:10)

Sammo ★

Continuity mistake: Spoiler; During the confrontation between the two last Indians, there is a clear position switch; her hair is in front or behind her shoulder when she says "This is how it hands." (01:23:05)

Sammo ★

Stupidity: Like in a previous movie adaptation (and unlike the novel), Lombard finds out way ahead of time that only another 'Indian' is left besides him, and knows they have the gun, but he lead them to the last body turning their back and leaving the gun to them, against any logic and declared purpose. It makes even less sense in this version than in the 1945 version, given the outcome. In the novel, the gun is stolen from him.

Sammo ★

Plot hole: Lombard is able to deduce that the doctor died hours before because there are no footprints around him, canceled by the snow that fell through the night. If that's so, then the doctor himself should have a considerable quantity of snow on his back and hair, and instead he has none. (01:22:40)

Sammo ★

Other mistake: There are heavy winds and persistent snow in an alpine resort, snowing every night, but throughout the whole movie even when Lombard goes to check the open door at night there's no hint of breath cloud on anybody.

Sammo ★

Continuity mistake: Ann is in bed with Lombard and after his reveal she asks him the name. Her hair was in front of her shoulder when she turned, and it's back behind it at the cut, and in front again at the next cut. (01:16:00)

Sammo ★

Other mistake: Lombard supposedly just pretended to drop the key inside the chandelier while he palmed it instead, but A) you can see the shadow of the key in the glass bowl and B) the noise comes with a timing and pitch that could be explained only by a key dropped, not banged against the rim. (01:11:05)

Sammo ★

Continuity mistake: And then there were four. They all are in the same room and Dr. Armstrong asks Ann Clyde what was she doing at the opposite end of the corridor. During the exchange, Shirley Eaton's hair is in front of her left shoulder but is or isn't in front of her right shoulder. (01:08:40)

Sammo ★

Revealing mistake: The suit of armor is knocked down by a hand, but when we see it fall there's a string pulling it for a more spectacular fall. (01:04:35)

Sammo ★

Continuity mistake: Lombard trips going up the stairs in the dark; he falls on his right side, but he waves the others to go up lying on the opposite side, facing the opposite way. (01:04:30)

Sammo ★

Continuity mistake: Judge Cannon's magical handkerchief misbehaves right at the beginning of the dinner scene when he tries to make everyone else confess; it's not even in sight when he gets his tea, but pokes out a great deal when in close-up starts admitting his own guilt. (01:01:35)

Sammo ★

Continuity mistake: During the various segments when the doctor and the judge are on their own while the others 'fix' (aka, break for good) the generator, a few times again the handkerchief in Cannon's pocket sticks out more - way more - in some shots, for instance when the doctor asks him to stop the game of cat and mouse. (00:59:40)

Sammo ★

Continuity mistake: Upstairs when Blore messes up the generator, the Judge and the Doctor are at a standoff with their matches. The doctor has a pool cue leaning against his shoulder in the front view, away from him in the reverse shot. (01:00:40)

Sammo ★

Continuity mistake: Blore threatens Lombard with a monkey wrench he holds with his thumb pointed up along the metal bar in close-ups, or just wrapped around it in the other angle. (01:00:05)

Sammo ★

Audio problem: In the boiler room, Blore responds to Lombard saying "I still wanna be a living idiot." In the next shot, Stanley Holloway's lips are moving with no sound before Shirley Eaton's arrival. (01:00:00)

Sammo ★

Continuity mistake: Blore is going in search of the generator, and the doctor approaches the light switch of the billiard room. In close-up the section of wall with the switch is nicely lit, but it is in the shadows in the camera angle encompassing the whole room. (00:58:20)

Sammo ★

Continuity mistake: When Miss Clyde, Blore and Lombard enter Ilona Bergen's room, the Judge's handkerchief sticks just with the tip from his pocket, but sticks much more in the next of the scene before he removes it. (00:56:00)

Sammo ★

Continuity mistake: When the doctor points at the arm of Ilona Bergen saying "Here's your bumblebee", it's in a straight line from the shoulder in close-up, but she is lying in bed with her arms pointing down. (00:56:00)

Sammo ★

Stupidity: Ilona Bergen's murder happening as shown is laughable; she sees the hand with the syringe coming, slowly, at her, and not only she can't defend herself or avoid it (because, damsels in distress in the 60s, you know), but she does not even scream. There's no way the killer could have been sure, or even take a calculated risk, to murder her in such a way. (00:55:25)
