Continuity mistake: When Annie and Laurie leave the hardware store to go to their babysitting jobs it is broad daylight. When they reach the houses apparently just a few blocks away, it is already dark.
Continuity mistake: When the old car blows up both of the dead zombies are gone. (00:21:40)
Continuity mistake: When the kids are drifting around, a heavy rain shower comes. Seconds later, in the shot of Sean on the upside-down sail boat, you see reflections of sunlight and a large part of the boat he is sitting on is completely dry.
Continuity mistake: After the second rape, on the rock, as Jennifer lays on the rock, her hair changes position between shots.
Continuity mistake: The dressing that is on the evil Dr Leticia Baines's forehead keeps changing. When she is first placed on Grogan's raft, the dressing is soaked with blood. In the next few scenes it just has a small patch of blood in the centre. After she swims to rescue the boy from his canoe, she gets on the raft and the dressing is dry. In the next two close-up shots the dressing is wet (with water) and then it is dry again.
Suggested correction: While the description of the events and the mistake is accurate, it wasn't Dr. Baines that swims out to save the boy. It was Dr. Hoak. You're thinking of the 1995 remake of the film.
Continuity mistake: When Mark dies his body falls to the ground falling forward. After Damien screams and goes over to him his body is now lying across the path.
Continuity mistake: When Gillian escapes from the facility, Hester runs out the door after her and collides with the guard coming from the opposite direction. For a second, they rebound in opposite directions, then it cuts and she falls on top of him (the same direction).
Continuity mistake: The burnout of Houston takes place at nighttime, but when the bees attack an ambulance driver who then crashes into a building, the scene changes briefly to broad daylight.
Continuity mistake: It is easy to see Ace Frehley was wearing black leather shirt/pants at the beginning of the film. When they are fighting the robots next to the Rollercoaster, his suit is white leather.
Continuity mistake: When Matthew goes to rescue Elizabeth from her boyfriend he parks on the street. When they leave he is parked in the driveway.
