Visible crew/equipment: While the winding road up the "bump" is being built, Ram is on the radio updating on the Legion's movements, and he says, "They're moving up hill 49, half a mile from our road." At the very start of the next shot when it cuts to Magda, Marcus, and Asher at the jeep, we can see the film crew's clapperboard in front of Kirk Douglas, as it swiftly moves offscreen at the bottom right side of screen.

Continuity mistake: Alva stands up from the swinging bench after the Hummingbird Express has passed. Sidney, by her, has his left hand firmly on the armrest, but the same arm is across his lap in the next shot as if he tried to reach for her. (00:22:30)
Continuity mistake: When Thomas answers the phone under the chair, there's a cushion with the number 3 written on it visible on the couch that changes position in the next shot when Jane stands in front of the window. (00:47:05 - 00:47:43)
