Continuity mistake: Michele Riondino has just killed the snitch and is going after the witness, a Chinese woman. He holds her at gunpoint; she does not move, but in a shot she has hair in front of just her left shoulder, both shoulders in the next. (00:30:30)
Factual error: Since the movie was set in the 60s, David Senak couldn't have gotten in trouble for shooting the man running away. In the 60s, the police could legally shoot any criminal running away. This didn't change until Tennessee v. Garner in 1985.
Continuity mistake: The glass bowl of spaghetti is filled within about 2" from the top, but the mound in the center almost reaches the rim when Janice carries it to the table. After Tim serves at least 1 cup servings onto 4 plates, the bowl looks just as full as it is when Edwin leaves the table. (00:14:27 - 00:16:17)
Continuity mistake: When Megan is outside the supermarket asking people to sign her petition, a woman walks up and begins writing on the clipboard. In the first shot, the cap is on the back side of the pen. From the next angle, the woman is scribbling and lifts the pen to show the cap covering the tip that she was "writing" with.
Continuity mistake: Izzy gets out of the car of her one night stand and lights up a cigarette. She begins to type on her phone, phone in the left, cig in the right. A jogger bumps her and in the next shot she coughs on purpose to try and make her put the cigarette out. From now on, Izzy's phone is in her right hand and her cigarette in her left hand. (00:08:05)
Factual error: Allegra was said at the end of the film to have died aged 10. She was actually 5 years old when she died.
Continuity mistake: Addison put his sweater on (over his neck and arms into the sleeves). After his dad asked him if he was OK, the view of Addison in the mirror showed him putting his sweater on again. (00:16:04)
Continuity mistake: Giorgio Selva meets a new barista, apparently fresh from university after a dissertation on Hannah Arendt. During this first scene with her, her ponytail moves back and in front of her shoulder. (00:03:50)
Factual error: Tony writes a "postcard" on the back of a picture to Adrian and Veronica to an address in Cambridge including the postcode. This scene occurs in 1967 (we see the date on the letter he is responding to) but postcodes weren't in use in Cambridge until at least 1970.
Visible crew/equipment: When Detective Hole enters the murderer's cabin you can see somebody running in the snow outside.
Continuity mistake: Gardner Lodge first takes a bite from the corner of the peanut butter and jelly sandwich and sets it back on the plate. The camera angle changes and when he is seen holding the sandwich again the bite is now taken from the middle of the sandwich. (01:28:55)
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)
Continuity mistake: When Saul and "Nookmis" (his grandmother Naomi) leave on the canoe, there are several blankets/rolls of food between them. The pile reaches to about Saul's waist in the canoe. When Saul and Naomi continue their canoe trip the following morning, the pile of blankets/rolls between them is higher (almost to Saul's shoulders) and the colors/sizes look different (larger, even though they obviously ate some food). (00:11:37 - 00:12:09)
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)
Continuity mistake: Lynn Jackson collects things from the desk and looks at George Pierce, who tells her "I'll talk to him", clutching his smartphone to his chest. Next shot and his arm is down his side. (00:18:10)
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: 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)
Visible crew/equipment: When Renton is singing at the pub, he approaches Simon playing the piano to let him sing a line. In the shot before he places the microphone under Simon's mouth, Renton is shown moving the microphone away from his mouth, and a camera can be seen attached to the microphone, to film the shots from the perspective of the microphone. (00:43:45)
Factual error: In the beginning of the movie, during Dickens' visit to America, you can hear them playing the melody from the song "I'm a Yankee Doodle Dandy" written by George M. Cohan in 1904. This was 61 years after the events in the movie. In the ending credits they cite this as "Yankee Doodle Dandy" which was written many years before. But, that was not the melody that was being played.
Continuity mistake: "Lean on Pete" and the car were obviously repositioned after the accident. The car hit Pete on his left side/legs, Pete's back landed on the hood, and Pete continued to roll over the roof and fell on the opposite side. It took a few cars lengths' distance for the car to come to a complete stop. Next, Pete was suddenly in front of the car, lying on his left side, and facing the direction he was running before the impact. (01:28:51)
