Continuity mistake: When Bill and Ralph pull up in front of the motel in Faultline, they see Pam walking out of her own room. The problem is Bill's room number is 127, the same as Pam's room number, also 127. (00:16:55)
Revealing mistake: At the paramilitary base, after Bill tells Bunker he has "a real cute bivouac goin'," it cuts to a shot of Ralph searching for Bill's location, and the stunt apparatus is visible at Ralph's waist area. (00:21:30)
Continuity mistake: At the paramilitary base, Bunker is wearing a military fatigue cap with a camouflage pattern while he and Bill are talking in the exterior shots, then when they walk into the office with the radar operator, in the interior shots the camouflage pattern on Bunker's cap is entirely different. When Bunker orders the evacuation, the cap reverts back to the original pattern in the exterior shots. (00:22:40)
Continuity mistake: At the laboratory in Needles, when Bunker removes the smallpox virus vial from the case he's wearing a digital watch and a ring on his left hand, but in the vial's closeup Bunker's ring has vanished and his watch is a different style. (00:43:15)
Revealing mistake: When Bill is pushed out of the helicopter and Ralph rescues him in mid-air, its obvious in some shots that it is two sky-divers dressed as Ralph and Bill. Firstly you can see the parachute back-pack bulges on both men. Also the wind is blowing up on Ralph even though he isn't meant to be descending.
