Continuity mistake: Near the end of the movie, when Oppenheimer is being interrogated in the small room, his lawyer is on the phone (we later find out it's Kitty). In a wide shot, he gives Oppenheimer the phone, and he puts it to his left ear. The next shot is a tight shot of Oppenheimer's face with the phone to his right ear.

Factual error: While handling the ignition coil cable to the distributor cap, Joe Pesci tells De Niro that the timing chain needs adjustment in his truck. A truck of that year with an inline Chevy motor would not have a timing chain at all, instead this truck would be equipped with a direct drive timing gear. Even if it had a timing chain, it would be behind the water pump and a cover. It would have been a several hour job to replace, not possible to adjust it.

Visible crew/equipment: At Hoover Dam, after the salute, when Defense Secretary Keller speaks with Lennox and Epps, the reflection of the white reflector screen is visible on Keller's glasses. What's more, the boom mic's reflection is actually visible within the reflector screen's reflection. Two for the price of one. (01:35:30)

Factual error: Kris is playing the original Gameboy and says he can't beat Bowser. No Mario game released before 1994 for the original Gameboy featured Bowser as a boss.

Question: In the scene right when they leave the hotel after the wild night, they see Doug's mattress. Is there any significance to the guy that turns to them and says some people just can't handle Vegas?

Continuity mistake: As Captain America arrives in his car at the airport car park, he stops right next to the line dividing the spots. In the following shot, when he steps out, the car is further away from the line, more towards the center of the spot. (01:26:50)

Plot hole: During the scene where Merida gives her speech on "breaking tradition", her mother, as a bear, moves silently behind the majority of the crowd, so they don't see her. Fair enough. However, Merida and her father's clan are all looking in the same general direction (towards the crowd) while she's speaking - how does no one from Merida's clan see a bear moving at the back of the room?

Grandpa Joe: Mr. Wonka! I don't know if you remember me, but I used to work here in the factory.
Willy Wonka: Were you one of those despicable spies who everyday tried to steal my life's work and sell it to those parasitic copycat candy making cads?
Grandpa Joe: No, sir.
Willy Wonka: Then wonderful, welcome back.

Continuity mistake: After Rey touches Luke's lightsaber she begins to have the vision, and when she falls to the floor the blaster is missing from the back of her belt, but after she "sees" Luke and R2 and then stands up the blaster is back again, tucked into her belt (even though Rey's having her vision of things all around her, she herself is not a vision).

Continuity mistake: When Carlotta brings the plates for the meal they all have a dome cover with a top handle, but when Sebastian runs across the table those handles have changed. (00:54:50)

Trivia: Not really a mistake, given the need for drama in a war film, but the mission takes place the evening before D-Day, meaning the Allies had complete air supremacy, and knew the exact time, date and place of the meeting of the German officers, this mission would never have taken place. The brightly lit chateau would have been flattened by a squadron of heavy bombers. Lee Marvin, an experienced combat veteran, pointed this out to the producers and was told to keep his opinions to himself.
