Visible crew/equipment: After the opening credits and intro at the start, in the first shot, just before the 'Britton and Sons Hats' glass door begins to open inward, the reflection of the camera and cameraman can be seen on the glass surface. (00:01:40)
Other mistake: When Stryker is killed at the end, it shows him lying on his back. Then, it cuts to a shot that shows the name on the back of his uniform. Who turned him over? (01:48:06)
Visible crew/equipment: When the acrobatic witness lifts Adam in the air, you can see the wires that really lifted him up.
Continuity mistake: In the final destruction-of-the-temple scene, the huge statue of Dagon starts to topple head first, but in later shots it is sliding towards the camera feet first. This is because director Cecil DeMille was not satisfied with the first take and had the temple re-erected then collapsed a second time. Shots from both destructions are spliced together in an exciting sequence, but rather puzzling architectually.

Continuity mistake: In the scene where Mary is eating her oatmeal while Martha is talking to her, take a look at Martha.

Visible crew/equipment: A wire is visible, attached to Lady Agatha d'Ascoyne's hot air balloon, as it sails across the screen. (00:55:10)
Plot hole: Immediately before the attack on Pony-That-Walks' village Capt. Brittles states that it's 12 minutes to midnight,and orders the attack. The attack is a surprise attack, yet all the warriors pile out of their tipi's fully clothed, painted and with their eagle feathers braided into their hair.
Continuity mistake: When the butler tells of Harry Lime's death, at the start of the conversation he can hardly speak English. As the conversation goes on, his English gets better and better, until at the end it's perfect with just an accent.
Suggested correction: He is reluctant to speak English at the start possibly to avoid trouble but later decides otherwise.

Mrs Waggett puts the tray on the left side of the screen, then, taking two cups with her, moves to the right of screen and that's where she stays when her husband finishes talking on the phone and, amazingly, the tray that was on the left side is now in her hands, without her moving to the left side to collect it.
Continuity mistake: After Tom has torn up Jerry's diary, you can see that the pie is next the hole of Jerry's home, but when Jerry comes around the corner and sees Tom, the pie is now positioned near Tom's foot.
