Factual error: Rhianna is watching a live feed of a man's office via webcam. We see a closeup of the screen. At the top it shows the filename being a ".jpeg." Jpegs are still image files, not movies, let alone live streams.

Factual error: Opening scene shows NYC 1962 as a 1964 Chevy Impala rolls by.

Factual error: The opening scene shows Donna graduating from New College in 1979. That is not possible, women were only first admitted in 1979.

Continuity mistake: Near the start when Wade and Vanessa are discussing families, in most shots facing her she's got her thumb lying along his jawline, but in most shots facing him it's sticking up by his ear.

Factual error: While bidding on eBay for the steering wheel, Vanelope tries to up the $350 bid by bidding $1,000. This scares off the real bidder, but Ralph and Vanelope don't understand how eBay works and bid against each other until they win with a $27,001 bid. That's not how eBay works. Vanelope's initial $1,000 bid wouldn't have set the high mark, but would simply have been her maximum bid in case the other bidder kept increasing his bid. The current high bid would have increased by the increment amount until it reached Vanelope's max bid. Now, it could be that the system recognized Ralph and Vanelope as separate bidders and that's why it let them keep upping the max bid. But, if the system had responded normally and simply increased Vanelope's bid to $355 with a max of $1,000, they might have realised what was going on and not started bidding randomly.

Continuity mistake: When English, Bough and his wife are looking at Garroch Castle from the submarine, Bough's wife says to English, "Jeremy has always spoken very highly of you." However, in the first Johnny English film, it was established that Bough's first name is Angus.

Factual error: In the second last scene, when Rachel is leaving Singapore for New York, Nick went onboard to propose, and convinced her to stay in Singapore for one more night. However, that's not possible in Singapore as there are strict laws stating that those that enter the departure area must have a boarding pass, with the purpose of leaving the country. Those that have a boarding pass but have no intention to depart the country will be prosecuted, and in 2018 40 people were arrested for various reasons, such as sending a friend off and meeting their idols, etc.

Plot hole: As shown when Robin comes under the influence of Slade's mind control device, the hypnotized people retain their abilities and higher intelligence, just with a loyalty to Slade. That being said, when Slade hypnotizes all the DC heroes, Superman and The Flash are among them in the theater. Slade orders all the heroes to chase after and destroy the Teen Titans. The Titans take off on foot with the others running after them and are able to keep their distance in a big chase sequence. Superman and The Flash never use their super speed to over take the Titans, which would have been so very easy.
