Revealing mistake: Bond escapes from the buried pipeline when two technicians open a hatch from the outside. One tech unlocks the hatch by rotating a large wheel, which drives the locking mechanism. But when he finally opens the hatch, there's absolutely no mechanism attached. There's just a bare axle that the wheel turns on.
Revealing mistake: When Charlie and Grandpa Joe drink the fizzy lifting drink and are floating in the air you can see the hook that is connected to the wire that Charlie is being held up by.
Revealing mistake: Just before the truck slides off the cliff edge, you can see that the truck's cab door is open where the stunt driver jumped out.
Revealing mistake: After Lansbury makes her clothes start to move, her nightgown attacks someone and you can notice the strings that make the gown move.
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.
Revealing mistake: During the driving scene, the background is illuminated by non-existent headlights. It's running backward on the projection screen.
Revealing mistake: When the bats invade Dr. Dunwoody's bedroom, you can see the strings on one of them.
Revealing mistake: Near the end the psycho killer pays a black man to beat him up so that he can then blame the injuries on Dirty Harry. Watch the killer's hairdo as he gets punched and beaten: a couple of rear-view scenes show an obviously fake wig, intended to look like the killer's own bad-hair-day style. (01:16:05)
Revealing mistake: In the slow motion crash of Steve McQueen's Porsche 917 you can clearly see that the car is empty.
Revealing mistake: At the beginning of the movie, when Kowalski is chased by cops on motorcycles on a dirt road, in the shots from behind the Challenger you can see two people in the car.
Revealing mistake: When the platoon hear the church bells, they mistake it for the invasion signal and construct a barricade across the high street. If you look behind them you can see cars parked on the road in the distance that date from well after the 1940s.
Revealing mistake: A 'bald wig' is visible on Harry Morgan when he first arrives in Purgatory.
Revealing mistake: Just before Hermie goes into the drug store to buy the condoms, you can see his breath when he is talking even though it's supposed to be summer time.
Revealing mistake: Early in the movie when the maid is opening the drapes to let in the morning sun, the sun lights the room a half a second before the drapes are actually opened.
Revealing mistake: Throughout the film, when the camera goes close to Zira, you can see the line where her wig is glued on.
Revealing mistake: When Shaft and his buds are sneaking into a building to save Bumpy's daughter, a pedestrian momentarily comes into the shot and then quickly steps out when he sees the camera crew. (01:18:45)
Suggested correction: I believe the entry refers to the initial rescue attempt, at 1:18:45. I am not entirely convinced that this is a legitimate goof though: the man sees 3 guys peeking into an alley, and he seems to rather stop and backtrack to check out whatever they are looking up, the exact opposite of 'stepping out'. It's still a rather amusing detail, though.
Revealing mistake: When Stan drives through a puddle and splashes Blakey the water just reaches Blakey's knees but in the close up the water that goes in Blake's face is obviously thrown at him from a bucket.
Revealing mistake: When Von Richthofen is shot down and crash-lands in the combat zone, German and British soldiers arrive and fight for possession of the Red Baron's plane. It is strange, though, that the German soldiers fire British Lee Enfield rifles instead of the German Mauser Gewehr 98.
Revealing mistake: When the doctors first arrive by helicopter in the town, they're looking around. The Minister lying upside down on the stairs moves his eyes and forehead as if looking to see what's going on, on the set. (00:22:15)
Revealing mistake: When Henry VIII runs out of the cowshed from the irate farmer, you can see it is not Sid James but his stunt double.
