Factual error: The title 'Publicity' is misspelled as 'Publicty' in the end credits.

Revealing: In the scene in the Mars Air/Spaceport, the troops are wearing Casio scientific calculators on their wrists.

Continuity: When Arnie is taking off his woman's head he presses a switch by the ear and the ear comes out. The device reaches right inside the fake head and there would be no room for Arnie's real head.

Continuity: When Arnie meets Bennie, he takes him to his cab and opens the door for him to get in. At that time, there's an explosion, and Bennie pulls the door down to shield himself and Arnie. The camera switches to behind them, and Bennie is just now pulling the door down.

Revealing: When Arnold jumps through the glass, you can definitely see a change in his face and body shape. (From the stuntman).

Revealing: When Arnie uses the dead body as a human shield, watch the corpse's mouth - he grimaces every time he gets hit (the squibs hurt).

Continuity: In the escalator scene when Arnie uses a corpse as a shield, there's a close-up of Arnie's gun firing, and we can see there's blood on the side of the corpse's head. However, in the wider shots there isn't.

Continuity: When Arnie comes home after killing his workmate, he pulls Sharon Stone to the floor. From one angle his hands are on her shoulders, from another they're on her elbows.

Continuity: When Arnold Schwarzenegger and Rachel Ticotin are being attacked by the giant drilling machine, Arnie grabs a pneumatic drill and cuts the main oil line of the machine, getting the left side of his face and his shirt doused in oil. Yet throughout the remainder of the film, there is no oil on Arnie's face or shirt.

Continuity: In the scene where Quaid unfolds a flyer for The Last Resort, he unfolds it with the flyer image facing the camera. When the scene cuts to him looking at it, the flyer image is facing him.

Continuity: In the scene where Michael Ironside's cronies are dragging Arnie to the service lift, watch Arnie's head: It changes from being flexed forward to being extended backwards as they swap camera angles. His hand positions change as well from shot to shot.

Continuity: When Doug is running from the bad guys after finding out what was going on from his "wife", he tucks his big gun in to his jacket pocket. When he is running through the scanner, that big gun is now in his pants.

Continuity: When Arnie uses the hologram projector in the alien reactor, there is a brief shot of him facing his own hologram image. Note that the gun and the projector switch positions in Arnie's hands - the bloodstain on his shirt's sleeve does not.

Revealing: When Quade shoots Dr. Edgemar, Lori yells "Now you've DONE IT.", and the wall explodes, which is plainly made of foam. Many of the pieces of 'wall' tumble lightly across the floor.

Continuity: A few minutes before Quaid kills his "wife", there's a shot of her with bright pink lipstick. Immediately before he shoots her, her lipstick is burgundy.
