The Omega Man (1971)

Visible crew/equipment: Very early on in the movie, Neville is happily driving around the deserted streets. Half way through this scene the camera shows us Neville's view out the front windscreen of the car. Ahead, moving cars can be seen crossing the intersection, obviously where the streets hadn't been blocked off for the filming of the movie.

Other mistake: Early in the movie, when Neville wrecks his car he takes the gas can out of his car and starts walking down the street. As he does they switch to a wide view of the city in which you see about three city blocks. When you look at the only "through" street in the shot, there is a car making a left hand turn about three blocks down that street and just behind the car is the freeway overpass with two or three cars passing on it, before the shot ends.

Revealing mistake: In the scene at the stadium where Lisa is helping Neville escape from Mathias' people, it is extremely obvious that in the far shots, it is a stunt man (wearing a very bad grey wig) driving the motorcycle, and Charlton Heston in the close up shots.

Matthias: You are discarded. You are the refuse of the past.
Neville: You are full of crap.

Neville: You know the old song? If you were the only girl in the world, and I was the only boy, well, okay, but until then, don't bother me? Well, I guess I'm the only boy.

Matthias: Definition of a scientist - a man who understands nothing until there was nothing left to understand.
Neville: So, there is a little light in the forest after all.
