Continuity mistake: In the shot before Josh hands in his preregistration sheet, he is not wearing his cross necklace around his neck. It was in shots prior to that, and is the focal point of the scene with the preregistration sheet. But in the shot where he is just walking, his clothes and all are the same, but no necklace. (00:03:30)
Continuity mistake: Azog kills Fili with his arm sword, running him through from back to front. In the next moment, when Azog tosses the dying Fili off the ledge, we see the arm sword - and it is shiny, clean and spotless.
Other mistake: At the beginning, when one bad guy is sitting on a bench with a newspaper, we can read the date October 21, 1959 at the top. But, we also read Nov 3 1970 on the same page, under the mugshot of the Boss being released from jail. (00:04:20)
Continuity mistake: In the scene where Corvus kidnaps Cassia and is racing through the city on his chariot, the street he is travelling down is completely devoid of rubble, bodies, and anything else that was already shown to be strewn across all of the streets.
Factual error: The movie depicted the use of obstetrical ultrasound. While ultrasound was first "perfected" in the late 1950s, it wasn't used in British hospitals until the 1970s and not in US hospitals until well into the 1970s, well past the setting of the movie in the 1960s.
Factual error: When Magneto enters RFK stadium, a groundskeeper is lining a baseball field. RFK stadium did not host baseball in 1973, as the Washington Senators had moved to Texas to become the Texas Rangers after the 1971 season. In 1973, the only team playing in RFK regularly was the Washington Redskins of the NFL. In addition, the Paris Peace Accords were signed in January of 1973; so there wouldn't be green grass inside the stadium, regardless of what sports were being played there.
Factual error: During the final fight, Liam Neeson jumps down an aisle to pick up the pistol that is hurled from the floor upwards in the air and shoots the villain in the head. The problem here is with physics. The plane was in radical descent moments before. The pilot eventually brings up the nose. At that moment, the gun and Liam Neeson himself would have been pinned to the floor.
Continuity mistake: In the beginning when Morton and Greg meet the drug dealers at the harbor, look at the big rig that is hooked up to the trailer. In the first few shots the truck brand is a Volvo, then when the truck drives away, it's an International.
Factual error: They find an old video camera from their dad, but that camera is already 10 years old. And the battery just works?
Continuity mistake: During Stoick's funeral Hiccup first shoots an arrow towards the ship and then the other characters draw their bows. Gobber is not shown as he is further away. In the next shot where they shoot their arrows, Valka and Eret are suddenly further apart from each other and Gobber has moved closer in between them. Eight arrows are shot simultaneously, but only seven arrows rain down.
Continuity mistake: When Jeanine looks at Tris' tattoo, there is hair covering the top of her ear. A few shots later, the hair covering her ear is suddenly behind her ear with only a strand of hair left over it. Then the hair is suddenly back to covering her ear as Jeanine goes to leave. (00:48:50)
Factual error: Tammy hits a buck with her car, which has polished antlers. The next day her and her grandmother are in the woods, and they see another buck, whose antlers aren't fully developed, still in velvet. These two scenes would have to be several months apart for antlers to be that different.
Continuity mistake: The necklace Stefan gives Maleficent appears and disappears as she is flying around the Moors. This is just after she gets the true love kiss.
Other mistake: In the scene that Callaghan's daughter went into the portal, there is a track for the capsule to go into the first portal, but there was no track for the return portal.
Continuity mistake: Soon after Jane meets Stephen at the beginning of the film she writes her telephone number on a napkin. Later when he looks at the number it is written much more clearly.
Continuity mistake: In the scene where Ava shoots Damien, she has no bra under her sheer nightgown in one shot and then has one when she goes to the window in the next.
Continuity mistake: In the scene where Logan carries Veronica into her room and covers her with the blanket, she is fully clothed. When she comes out to ask him, "don't go," and then kisses him, she is not wearing pants and has a different shirt.
Audio problem: When Jonas first shows Lily how to dance, then caught and asked what he is doing, Lily responds with "Jonas says it's called dancing." The audio is added in in post production. Lily is smiling at Jonas without moving her lips. (00:37:00)
Other mistake: Since the vacation was supposed to be for Dick, Jen and Dick's five kids, the hotel suite kids' room should have had five beds, not four.
Continuity mistake: Federov is pointing a Wather at a kneeling Mira. In the next shot his gun switches to a Sig-Sauer and then back to a Walther. (01:12:55)
