Audio problem: There is a scene where the mistress of the murderer enters his bureau. You see her push the door closed while hastening through. You can hear the door lock click - but a half second too early. Her push wasn't that strong. (00:47:05)
Audio problem: In the last shot of the shoot-out scene at the station, we see Harmonica's carrier bag in the extreme foreground, and windmill in the extreme background. The windmill has stopped, but you still hear the wind blowing, and a few seconds before you have heard the squeaking pump. (00:13:50)
Audio problem: In the scene where Chitty Chitty Bang Bang is passing the train you can see a continuous trail of smoke issuing from the train. It is exiting from the train's whistle, meaning that there should be a continuous high pitched whistling noise, yet there is no such thing.
Audio problem: In the scene where Ben nails the door to the wall to keep the zombies out, the sound of the hammer hitting the nail is inconsistent with the pacing Ben actually hits the nail.
Audio problem: Guy flushes the toilet as he walks through the bathroom. The toilet is actually empty and the sound is an over-dub because there is no resistance on the handle when he pushes it down. Had an old toilet like that actually been full you would see the resistance in the lever as the flapper inside rises. (00:04:45)????
