Continuity mistake: At the end, when Gloria hurls Oscar completely out of sight beyond the horizon, a huge crowd of South Koreans rush up directly behind Gloria, cheering and applauding, only a few feet away from her. The camera cuts to a frontal shot of Gloria, and now the crowd is 30 feet or more in the background.
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)
Continuity mistake: The level of snake wine changes in the glass as the camera cuts back and forth during the conversation in the Chinese restaurant between Jeff and Tim.
Revealing mistake: In the opening scenes, we see a very pregnant Draka reclining on a bed of animal hides as Durotan watches over her. In the extreme closeup, we see Draka twitch her lips, and her small tusks flex from side-to-side with her lips, instead of remaining firmly aligned with her jaw as they should.
Continuity mistake: In the first scene, the old alien man comes to pick up his spaceship and Ratchet instructs him to "Now, let's fire up that mag booster." The old alien pushes the switch forward to start the mag booster. Later in the movie, Ratchet flips the switch backwards to "engage mag booster" as Clank commands. (00:06:30 - 00:26:30)
Factual error: A bullhorn can be heard in the background off-screen during a battle with the zombies, even though the movie takes place during Victorian times. (01:19:30)
Continuity mistake: After their fight with the monkey Sara has some scratches on her forehead and cheekbone but when she gets to the castle with Freya they are gone.
