Continuity mistake: At the beginning of the movie, the hunter is looking for his dog. The rifle on his shoulder keeps changing position, being upside down or not - which is easy to spot because of the big scope. (00:01:30)
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: When Gabby and Fin are hanging off the building in Las Vegas, you can see that Gabby isn't holding on to anything in some close-up shots. (00:11:47)
Other mistake: The typewriter ribbon in Gemma Arterton's typewriter looks to be installed upside down, with the red half of the ribbon showing above the black half.
Other mistake: When Warwick Davis shows Joe the form he's tricked his father into signing to allow him to transfer schools, the form is shown full screen. The "home" phone number is the same as that used in the school's letterhead, and there is text that says"insert name of fictitious school here." Also in this scene the name of the headmaster and phone number is visible, but none of those details match what is on the school's advertising board a couple of scenes later when Joe starts at his new school.
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.
