Revealing mistake: In the London scene, when the main characters prepare for the Centipede attack (the scene with the football players) there is a grey Land Rover which has a fake UK number plate on it. Plus since the film was filmed in Canada, the car also has left hand drive windscreen wipers.
Continuity mistake: When playing Donkey Kong in the competition, Cooper finishes Level 22 by jumping over the last piece holding the Ape up and then it says "GAME OVER," when he should go to the next level.
Factual error: At the start of the 1982 Arcade competition (right after Dan Aykroyd says "start your gaming"), a man imitates a move from the "karate kid" (the crane kick). The movie Karate Kid came out in 1984 (2 years after the competition). (00:06:11)
Continuity mistake: While the Indian guy is taking a shot of the pixel attacking the Taj Mahal, his cell phone switches hands between shots.
Continuity mistake: When Sam kisses Violet at the end of the film, the sun changes between shots.
Factual error: When Sam and Will walk into the venue hosting the 1982 Worldwide Vieo Arcade Championship you can see some kids playing on a Zaxxon machine. Zaxxon was released in December, 1982.
Character mistake: Lt Col Van Patten's ribbons are out of order.
Character mistake: Violet is in the Army, but does not have her hair up properly in uniform.
Other mistake: When Matty and Sam are having a conversation about modern games vs older games, Matty is playing a game on a Playstation 4 but the controller isn't on.
