Continuity mistake: When Nicholas Cage and his kid are enjoying a flashback, the ice lolly keeps shrinking and growing throughout the conversation. (01:14:00 - 01:15:00)
Factual error: In the movie the professor's assistant says thst the professor was in OSS in the great war (WWI). OSS was first formed in 1941 by President Roosevelt.
Factual error: Performing for Queen Victoria is the famous opera composer Giacomo Puccini. This happens during her sojourn in Florence in 1888. Puccini was born in 1858, so he was barely thirty years of age, but the actor portraying him, Simon Callow, is in his late 60s (and it shows). Moreover, he is presenting his latest creation "Manon Lescaut"; in 1888 he hadn't even started working on it.
Continuity mistake: In week 14, at his wife's request, the reverend goes visit Ye Win to ask him about increasing work shifts. When he is shown handing back forms to his fellow Burmese people, Ye Win puts down his pencil, but the pencil is back in his hand when he is passing the first. (00:57:10)
Factual error: Engine 463's firebox is seen in a close-up, revealing a cast in date mark of 1914. The caption near the start says it's set in 1892. (02:02:00)
Plot hole: There's no way that plane could have crashed and stayed intact like it did.
Continuity mistake: Sara recovers the artifact and gets on the boat. She removes the deep-dive helmet and the oxygen tank. The villain is looking at her through his binoculars, she hasn't moved, but the equipment she took off and dropped on the deck has vanished. (00:03:00)
Revealing mistake: The bartender (Kateryna Korchynska) offers Ethan two lattes on the house. She hands them to him, and he walks out. No opacity from the liquid can be seen inside the plastic cups, and when he is moving away from the counter he leans forward quite a bit, showing the inside of the cups, squeaky clean. (00:08:00)
Factual error: There are references to failures of novels by Dickens that were actually not written until after the events depicted in the film (e.g. Martin Chuzzlewit and Romney and Son).
Continuity mistake: The team has to come up with a plan to handle The Truth. Destiny's friend Willow stands up and says "So look, here's my plan." Destiny announces she has a better one; during this exchange, the phone in Cristine Prosperi's hand switches hands. (00:11:30)
Continuity mistake: Gabby is just starting her assignment. She is looking at the women of the choir singing "Joy to the world"; she is standing at distance from the pews, but when it cuts to a closer view she has her hands on one. (00:10:00)
Continuity mistake: Michael sets foot into the church and meets Pastor John Soul. John has a clipboard in his left hand, as well as his glasses, as he says "But the doors of this church are always open to you." He opens his arms and the glasses are in the left hand. However in the wider shot that follows ("But, if you are looking for redemption...") here's the Pastor with the glasses in his right hand. (00:27:05)
Factual error: Emmanuelle Devos goes to the airport to get her husband and daughter. Their plane landed at 7 PM (18:58 to be precise) as shown by the airport monitor. They get a cab to a hotel downtown, and then there's a scene when she books a restaurant from the hotel room. She tells her husband, who just took a shower, that they need to be at the restaurant at 8 PM. Her husband says that there's no rush then, since it's only 7 PM. Of course that's impossible, the Turin airport is about 20km away from the part of the city they are driving through, which at that hour has also significant traffic; if their plane landed at 7, at 8 PM they would hardly have any time left to spare. (00:29:00)
Continuity mistake: When Kat wakes up for the second go-around of Valentine's Day (the first repetition), she scoffs at the text from Bradley, her date who bailed on her. When the text is inserted onscreen, it matches the original day's, mentioning their planned dinner and first in-person meeting. When her phone's actual screen is shown, the text from Bradley is an invitation to breakfast. They never had or planned a breakfast. The wording is very similar to Danny's invitation at the end of the movie.
Visible crew/equipment: When they get into the tunnel/water drain, you can see the crew on the left side when switching the scene. (00:39:00)
Continuity mistake: The candle to the far right in the candelabra is tilted to the right to various degrees or not in between shots. (The other candles aren't exactly straight up.) In one shot, the candles are further apart (not paced the same distance between them). The top half of the candelabra was tilted to the right when the right candle was leaning against the wall. (00:24:27 - 00:25:20)
Continuity mistake: In the first episode, the cold Federico is shaken by the first approach with the bookstore owner Giulia. When he comes back inside the store, the woman is leaning against the corner of table when the camera is in front of her, she isn't in the shots from the back of the store. (00:04:30)
Continuity mistake: When Toni Servillo meets Verónica Echegui in the sauna, she says something in Spanish to him, and then shrugs in a close-up. The jacket and towel cover her shoulders and neck area entirely, but in the wider shot that follows, the towel is gone and the jacket is looser. (00:11:10)
Continuity mistake: Throughout the scene at Stukey's, when Helen Mirren is chatting the Syrians' ears off her elbow sticks out of the window at variable length between shots. (00:05:45)
Continuity mistake: Jake and Wendall are talking on the track field as they pull some weights. The strap attached to Wendall's glasses keeps moving in front and behind his shoulder between shots. (00:03:30)
