Other mistake: In the very last scene of the movie, and just before Blondie shoots the rope that is holding Tuco on the grave's cross. You can see a car moving in the background, screen right of Tuco's head.
Other mistake: When Hamm turns off the TV at the beginning, there's no reflection of him, Rex who is beside him, or the remote. (00:06:58)
Other mistake: The crew goes up to Calgary in January to extinguish an oil fire, yet there's no snow on the ground, the grass is green, and all the deciduous trees have leaves.
Other mistake: Near the end of the closing credits, when the Warner Bros. Copyright appears, you'll see the very first word "All" spelled incorrectly as "Al" in "All material is protected by Copyright Laws of the United States and other countries throughout the world." (01:26:40)
Other mistake: DVD and Blu-ray only: in the Battle of Endor, right after the rebel fighter says "there's too many of them." The Millennium Falcon goes into 1/4 of the picture, you can see a black square spot on the right side of the flash frame due to a bad filter usage. Widescreen only. It does not appear in the 4K release even though it wasn't removed.
Other mistake: When Leela is signing the petition, Amy grows a third arm for a split second.
Other mistake: As Dark Helmet says his line "Everybody knows that!", watch the crewman in white to Helmet's right. He starts to cover his crotch a beat too soon.
Other mistake: Towards the end when we see one of the $100 bill plates up close, the plate is not of any money ever put into production in the US. While I know most movies do not try and use actual money, there are things that don't match how real money is made: serial numbers are not on the plates, circle around Ben's head doesn't go to the border, "The United States of America" is missing above the "100" on the left, just to name a few.
Other mistake: On one of the SHIELD monitors, "perimeter" is spelled "perimiter".
Other mistake: There is a scene where a dead Indian warrior is discovered. In this scene he is covered by a large flat piece of stone. When they pull away the stone you can see his chest rising and falling as the "dead" Indian breathes. Much easier to see when viewed in HD.
Other mistake: When Westley and Buttercup are in the fire swamp and Buttercup is burned for the first time look carefully at the fire spurt, it's several feet away from Buttercup and is clearly too far away to have burned her.
Other mistake: In the scene where Paolo leaves the stage after everyone discovers that he can't sing, his bodyguard Serge stops him and Paolo suddenly loses his Italian accent. Paolo sounds very American when he says "You work for me, Serge."
Other mistake: When a glass of milk is poured, if you look closely, the glass is filled but the level of milk in the bottle doesn't seem to lower. (00:16:00)
Other mistake: Teddy's hair changes in every shot after being dunked in the swamp. The strap to his bag disappears and reappears as well.
Other mistake: When James Bond's friend Kerim Bey gets shot at the gypsy camp, look closely: he is rubbing fake blood into his own arm. (00:43:10)
Other mistake: Meowth calls one particular Pokémon in the test tube-thing a Sandshrew, however it is a Sandslash. This is a dubbing error, as Nyasu (Meowth's Japanese name) correctly identifies the Pokémon as a Sandopan (Sandslash's Japanese name) in the original Japanese version. (00:58:26)
Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.
Other mistake: The knife used in the Argentina pub scene never has any blood on it, despite being driven into one man's stomach and another man's hand-twice.
Other mistake: Davis tells Kate to go and she jumps out of the falling plane, her chute opening. Davis then takes a minute to free Harvey from the plane as it's still falling before they both get out. Once they are free falling he takes a few seconds before he pulls their chutes as well. However as they are coming down close to the plane crash site, Kate is near level with them in altitude as they are all coming down together. With how high she was when she jumped out compared to the time it took for Davis and Harvey to get out of the plane and open their chutes, she would have been several minutes behind them in the sky, not right next to them. (00:47:45 - 00:49:05)
Suggested correction: She jumped first and would have already descended in altitude. Then the guys jump and freefalled and pulled their chutes so it is plausible they caught up to her altitude when their chutes opened.
Other mistake: Whenever Verne is inside his shell, he has a tail (and references to it "tingling" are made throughout the movie), however, when he is out of his shell he has human-style buttocks and no tail.
