Midnight Madness (1980) - 5 major mistakes

Continuity: When at the poolside of the Bonaventure Hotel, Adam looks at one of the express elevators ascending. Then he turns and runs for the elevators, followed by the blue team. Miraculously, both elevators are now at the bottom floor.

Continuity: When Harold is at the drive-in diner, he grabs his fries with his left hand and then pushes the window tray off of his car with his right hand. In the next shot the fries are in his right hand, there was not enough time for him to switch hands between shots.

Deliberate "mistake": Blaylak was extremely intoxicated when the Green team first got to the mini-golf place but he was stone cold sober just minutes later when the White team confronted them about their poor sportsmanship.

Deliberate "mistake": The 27th floor is very tiny indeed, despite the outside view showing it to be as big as any other floor. On one end is the stairway. On the opposite side is the elevator Adam's team rides up in. There are only 4 rooms total, and between two of the room doors is the elevator ridden by the security guards. Also, logistically, the security Guard's elevator cannot be there if you notice the area at ground level where Adam's team enters their elevator.

Revealing: While in the Bonaventure hotel, the white team poses as bellboys and helps an old lady and her barking dog onto the elevator. The dog inside the canine caddy is obviously stuffed.
