Visible crew/equipment: Very close to the beginning of the film, when they first land the helicopter in the abandoned city, there is an alligator on the steps of a bank. A few seconds later when a zombie comes out of the bank and the alligator runs down the steps, you can see a red band covering his mouth (that wasn't there before) to prevent him from biting the actor.

Day of the Dead (1985)
1 visible crew/equipment mistake
Directed by: George A. Romero
Starring: Jarlath Conroy, Joseph Pilato, Lori Cardille, Terry Alexander
Revealing mistake: In the very beginning when we are flying over the dead town in a helicopter, look closely at one of the very first shots of the "empty" city. On one of the left side streets you can see a car driving down the road. It's not a character mistake because she is looking hard out the window and should have spotted the moving car.
John: I got an alternative, yeah, yeah, I got an alternative. Let's get in that old whirly-bird, find us an island some place, get juiced up and spend what time we got left soakin' up some sunshine! How's that?
Sarah: You could do that, couldn't you? With all that's going on, you could just do that without a second thought?
John: Right, I could do that even if all this wasn't going on.
Trivia: Lori Cardille, who plays Sarah, is the daughter of Bill "Chilly Willy" Cardille, who played the newscaster that talks to the sheriff in the original Night of the Living Dead.
