Continuity mistake: While Eddie performs "Hot Patootie", he's seated on the motorcycle with Columbia for a bit, and when Eddie stands up he's holding the mic in his left hand, but as he walks up the steps it's in his right hand, then next shot when he's facing Frank-N-Furter the mic is in Eddie's left hand, and next shot it's back to his right hand again.
Factual error: James is playing his guitar outside a station. Before the frontal shot that identifies it as Covent Garden, there's a street poster for the musical version of "Matilda." The play was already in existence in the movie timeframe, but the poster is in its "Believe the hype" version that is post 2013. The movie ends in 2012. (00:19:55)
Continuity mistake: In the 3 wheeled vehicle, Bennie is driving and Conner says "Women do not go for that whole constipated Debbie Downer look." A shot shows Bennie's hair blowing wildly in the wind, then cuts to a view from Conner and suddenly Bennie's hair is straight and still, then cuts again and once again his hair is blowing. (00:39:45)
Deliberate mistake: The movie is set in the late 50s, but Howard Hughes is dealing with his plane crash and the senate hearing about the H-4 Hercules prototype. Those are events from over a decade earlier. However, it should be noted that the initial disclaimer of the movie is "Names and dates have been changed."
Continuity mistake: Carolyn puts on her pink dress and asks Tallulah to zip her up. Tammy Blanchard puts her hair up in a bunch, but there's a large bang to the left side of her face that stays down. In the reverse shot though, she got all her hair up. (00:18:20)
Continuity mistake: The old man in the hotel lobby pulls the flowers out of the megaphone and calls the protagonist. She lowers the headset to talk to him. The left speaker is all the way across the opposite side of the neck in the first shot, less shifted to that side in close-up. (00:04:00)
Factual error: Kim is seen using a first generation iPhone in the 2006 scenes. The iPhone was not released until summer 2007.
Continuity mistake: When Lady Susan is counseling her daughter Frederica in her bedroom, the shot shows an unlit candle on a dresser behind Lady Susan. The shot changes back and forth between Frederica and Lady Susan. When the shot changes back to Lady Susan, the unlit candle is gone, though there is no one else in the room.
Continuity mistake: Mother and son run towards the store window as the Ford Galaxy is burning in the parking lot. At the end of the shot from behind, a woman with a lilac top and long brown hair comes into frame and leans against the vegetable stand. After the cut, with Jamie and the mom by the window, the same woman walks in again. (00:01:30)
Other mistake: Augustina approaches "Bill at the bar. The bar's clock shows it's 9:12. The two go on to talk for over 2 minutes of real time, and she says "it was so 10 minutes ago" when he quotes an earlier bit of the conversation; no matter how much time it passed, the clock did not advance. (00:02:10 - 00:04:10)
Audio problem: In the final conversation between Limus and Bardot, the robotic effect usually applied to her voice is missing.
Continuity mistake: When Michelle gets catapulted onto the wall and begins wailing, her right arm is straight, semi-parallel to her shoulders. Next shot and it is bent, hand up to the level of her face. (00:22:55)

Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
Factual error: After the death of his beloved pet turtle, Conner is on a downward spiral. One of the headlines that appear as paparazzi follow him (before he gets KTFO'd by Martin Sheen) has a "Friday August 08, 2015" date. Which was a Saturday. (00:58:10)
Continuity mistake: At the toll booth, Afonso does a thumb up sign to the operator, not knowing what he really said to his son about their ride. He is doing the gesture with his right hand, left hand, right hand again depending on the shot. (00:07:00)
Continuity mistake: In front of the station, the con man bargains with the taxi driver the fare; during the scene, the same black man with a floral shirt passes at least 3 times. (00:01:30)
Continuity mistake: Near the end of the film when Robert De Niro gets to make out with the college girl, the switches between camera shots show his shirt off and subsequently back on again.
Continuity mistake: When Masovich kills Paolo, we see the slide stay locked in the open position. But in the next shot the slide is closed.
Continuity mistake: When Chaz leaves the house telling Jesse that she has just 2 weeks to pack, in the close-up when she says "Bye..." her hair is all in front of her shoulders as opposed to the rest of the scene. (00:08:40)
