Other mistake: When the setup for the first match is announced, the Ram is said to fight Tommy Rotten "for the strap", which is pro wrestling slang for a belt, meaning it was a title match. But after the match, which he won legitimately, The Ram is not announced as a new champion, nor is he ever referred to as such, and no belt is given to him after the match.
Continuity mistake: When the Ace Gang are sitting down talking about the snogging scale, Rosie has a lip gloss, passes it to Jas, Jas uses it, gives it back to Rosie, who gives it to Ellen, Ellen uses it, then gives it to Georgia. In the next shot, Rosie has it again without it being passed back along.
Visible crew/equipment: When the subway train with Annie and Will departs (the train goes to the right side of the screen), there's a close-up of the train. Then, in the lower right corner (during two seconds) you can see a camera, a cameraman and two crew members next to it, reflected on the windows and the shiny surface. (00:46:00)
Continuity mistake: When Zack is talking to Deacon at the hockey game, there's a water bottle between them. It disappears during the rest of the scene, even if the two characters are not seen drinking. (00:35:00)
Continuity mistake: When Oskar shows his Rubik's Cube to Eli and explains how it works, one side is all white except one square, which differs from being red vs. blue between shots.
Factual error: When Meryl Streep is walking outside and talking to Mrs. Miller about the potential abuses of her son, you can see a basketball court in the background and on the court is a 3-point line. The movie is supposed to take place in 1964 and the 3 point line wasn't introduced until 1979/1980. (01:10:20)
Continuity mistake: The pile of eggs that Bud knocks over in the security video becomes noticeably smaller when the angle changes.
Factual error: The doctor parks his car under the house before the storm hits. Since the house is on the beach and the wind and water hit the house, there is no way his car would start and be so clean after such a storm.
Continuity mistake: When the girls are having their PE lesson and Poppy is watching them practice their Lacrosse skills, Poppy gets some mud on her face, but in the next shot as she is putting sanitizer on, the splatter of mud is bigger and has changed shape. It is before she has touched it so it wouldn't have spread yet.
Factual error: In the film, Sgt. Jack Lupino is depicted as a United States Marine Corp Sargent. However, when Max is watching an interview with Lupino it shows him wearing either a Gunnery Sargent or Master Sargent chevrons. Not only that, but the chevrons happen to be upside down. No US Marine would ever make a mistake like that.
Factual error: When Chuck is stapling fliers to the telephone poles, the tree behind Vanessa has changed colors for Fall, but still has a lot of orange leaves. The scene takes place after Christmas. In Pittsburgh, PA, the leaves are long gone by December.
Factual error: The Moon is pushed into a "more elliptical" orbit. When the orbit it shown, it is more eccentric than the Moon's real orbit. However, it is centered directly on the Earth. This violates Kepler's first law of motion, which states that a natural satellite has the primary body at one focus of an elliptical orbit. In other words, the Moon should come much closer to the Earth at one end of the ellipse, and recede very far from it at the other end, rather than receding to the same distance in both directions.
Other mistake: When Meg Ryan is getting out of her black Lexus in front of her house (about 8 minutes into the movie), you can see that it is late in the afternoon by the shadows of the bushes and the trees being cast on the ground. However, she's rushing into the house to throw a 12:30 luncheon. If it were actually 12:30, the sun would be high in the sky and there would be very little shadows cast on the ground. (00:08:20)
Factual error: A woman is shown receiving electroshock treatment ("ECT") in a hospital scene which took place in 1928. Although chemicals were used to induce seizures in psychiatric treatments at the time, the use of electricity for the purpose was not discovered until 1937 and not used in the United States until 1940.
Continuity mistake: Near the end, the tank's turret is seen turning. Camera does a quick cut and it's back to where it was before. Camera cuts and it's turning again.
Factual error: When the soldiers return to HQs, the American flag, hung vertically over the entrance, has the blue field with stars on the right. The flag, when hung vertically, is supposed to have the blue field on the left..
Factual error: There are Velcro straps holding the pads on the blocking sled, and there is an end zone goal post with one base. Both of these items did not exist until the late 60s.
Continuity mistake: When the mayor of San Francisco signs the new 'gay rights bill,' he puts the pen to paper with his left hand in the far away shot. When the camera cuts to the close up of him signing the bill, he's writing with his right hand.
Factual error: The scene that takes place at the Ford release of their 1971 models has two Mustangs driving to the event. The one in front is obviously a 1973.
Continuity mistake: When Dacyshyn drags Mulder by his legs and brings him to the shed, he goes past the tree stump with an axe embedded in it, but in the close-up of Mulder's torso there is some debris on the tree stump and the axe has disappeared, then the axe reappears still embedded in the wood.
