Revealing mistake: When Anna and Hans are dancing in front of the lighthouse, we don't see the shadow of the railing or the ground they're standing on.
Character mistake: When Katie's husband arrives in town and confronts her on the night of July 4th, he says "I miss you Katie." He does not know her name to be Katie as that is the name she created when she came to town. He is married to Erin.
Suggested correction: He says "I miss you, baby" and then "I miss you so much, baby."
Continuity mistake: During the dinner scene at Tom's, a couple of shots before Tom's phone rings and he goes to answer it, Nick's wine glass is about half full. After Daisy leaves to go to Tom and the shot cuts back to Nick, the level of wine in his glass has notably decreased, without him touching it. (00:09:50)
Continuity mistake: When Theodore goes to Amy for comfort in her apartment, there's someone (or something), walking at the front door, but then not again in the next shot. Keep your eyes top right, it's very visible. (01:26:50)
Revealing mistake: Early on, after Clary blasts the demon with a homemade explosion that blows a huge fireball across the kitchen and blasts out the window, there is no sign of anything being burned, not even the curtains. The kitchen is only in a slight shambles and there are small fires burning in isolated areas that never spread or char anything.
Factual error: At the end, Josh and Nat both run onto the Eurostar platform when they do not have a train ticket - this would be impossible, since there are ticket barriers and security.
Factual error: At Liberace's funeral, when the priest concludes his prayer, the congregation responds, "And with your Spirit." This response has only been part of the English-language Catholic Mass since 2011. In 1987, the response would have been "And also with you."
Continuity mistake: When Romeo gives his hand to Juliet on the balcony before descending, he gives his right hand to Juliet. Immediately his left hand is shown in Juliet's, then his right hand is shown in hers again.
Continuity mistake: When Chantry is in Dublin writing her list, the list reads: Toronto - My Job - My Family - My Friends - My Life - Wallace. In the next shot of the list, it just reads: My Friends - My Life - Wallace. The first three entries on the list disappear.
Continuity mistake: At the beginning, as Raimund is crossing the bridge in the rain, his umbrella turns inside out, but as it flies away to the river, it is not turned.
Factual error: Tilda Swinton requests a flight from Detroit to Tangier, Morocco, but it must be an all-night flight since she and Tom Hiddleston are vampires. They end up accepting a flight connecting through Madrid. Flying west to east, it would be impossible. If they leave their home at sunset, say 6 p.m. Detroit time, and take off around 8 p.m. Detroit time, it is already 1 a.m. In Spain. Toss in the travel time and they will be landing in Madrid in the early morning, which would kill them.
Continuity mistake: The protagonist at the beginning of the movie sunbathes topless.The camera is positioned where the kid is spying her, and in that wide shot she is placing the garment she removed close to her lower half of the body. When he waves his hand casting a shadow over her eyes, the bikini top is in the corner of the towel next to her head. (00:01:20)
Continuity mistake: When the awful cousin Charlotte hands Gwen the slice of unbirthday cake, she does it with her right hand, left hand, right hand. (00:04:20)
Continuity mistake: Notice how Julie pumps her shotgun twice within a few seconds in the lab without once firing.
