Other mistake: Although the Lieutenant is actually sent to the police station in precinct 9, division 13, the sign over the door states it to be division 14.
Other mistake: The chronology of dates on the teletype printer at the end of the film are not in the correct order. We see "March 13, 1975" followed by "January 3, 1975", which is then followed by two August 1974 dates.
Revealing mistake: At the end of the film, when Tony crashes Tim's car at the driving test centre, you can see it has been changed for a wreck as just before he crashes there is damage to the front left hand side that wasn't there before.
Continuity mistake: When the soldier demonstrates the bazooka on a truck, the projectile hits the front of the truck, but the explosion comes from near the back of the truck.
Continuity mistake: The first time William Holden and Faye Dunaway have dinner together, Holden's lit cigarette changes length several times in both directions.
Continuity mistake: John Norman (Kris Kristofferson) and Esther Hoffman (Barbra Streisand) are sitting at the table talking. John opens a bottle of wine and every time the shot faces John the cap is on, but when the shot faces Esther the cap is off, over and over again.
Continuity mistake: In the marching band scene, the band casts long shadows - then NO shadows - then long shadows again (repeatedly).
Continuity mistake: Right at the end when the man takes his mask off, a strand of blonde hair hangs out from the back of "his" head. In the next shot the hair is dark brown.
Continuity mistake: In the masked ball scene, St. Ives grabs a party goer and steals his mask which you then see him putting on. It is a gold mask without any markings that covers most of his face, but a few moments later when St. Ives dances with Flora, he is wearing a much smaller gold mask with black decorative markings.
Continuity mistake: When Mother is pulling up to the burger joint, you see his partner with his car window open. He's even resting his arm on the door. The camera angle changes as they pull up to the drive through and you see his partner lowering his window down so they can place an order.
Factual error: In the scene where Cinderella is in her new room at the Prince's castle, the roses prominently displayed in the foreground are brightly coloured Hybrid Tea roses (the pointy ones) which were not bred until the early 20th Century. In the 1700s (panniered skirts and powdered hair) the roses would have been of looser formation, with softer colours, e.g pink or cream cabbage roses. (These roses also appear in later scenes.)
Continuity mistake: In the scene where Bruce Dern and Barbara Harris are eating hamburgers. He has two on his plate, from a back view she reaches over and takes one. He then removes the cap from the ketchup bottle. The shot switches to a view from his back and the cap is back on the ketchup. He then removes the cap again.
Revealing mistake: During the scene when David is fighting off the large beast in the arena, there is a shot where you are looking right down its throat. Inside the "creature" you can see a light emanating from inside the mouth of the suit, probably so the actor inside could see while acting in it.
Factual error: At the start of the movie, the nuclear-powered articulated bus that is attempting a non-stop land run to Denver leaves New York City, but you can see the Rocky Mountains in the background.
Continuity mistake: When the psychiatrist is holding up the horse figurine, the way she's holding it in the closeup is quite different than in the wide shot.
Factual error: About 3/4 into the movie, in the scene where Woody is looking for a place to sleep, he comes upon this other man in a bunk. The guy in the bunk asks Woody if he wants to share his blanket with him because it is cold. Arlo does. In the next scene, outside, it shows the steam locomotive, and to the left of the steamer is a diesel locomotive. It is a Western Pacific GE logo. The movie is 1936 and WP diesels didn't show up till 1953. I was there.
Visible crew/equipment: As Mario emerges into the house from the rain to get the bodies, a crew member is seen when he opens the second door. (01:04:05)
Revealing mistake: When the supervisor is telling Geronimo to clean up the dog feces, there are three men across the street in front of Al's Coffee Shop watching the filming. (00:42:55)
Continuity mistake: When Christella is slapped by the possessed Ike, her pose changes between shots.
Plot hole: Funn, Eggs, and Bell, accompanied by Vilma, enter the theater, ready to show their finished Silent Movie project to the audience. However, only a night previous, Funn, inebriated, is rescued from the gutter, by his friends. A scene immediately following, shows them 'reviving' him with coffee. When did they find ample time to shoot their film? The time frame doesn't add up.
