Character mistake: When Spoken Reasons describes Kaitlin Olson, he says she has brown eyes. She has blue/green eyes.
Character mistake: On the tour boat in London, the voice on the loudspeaker says 'if you look to your right, you will see the Tower of London'. Except it's on the left, given the direction the boat is travelling. (00:53:00)
Character mistake: At the party, Fred is supposed to make a bbq, feeding about 50 people. But once he's got the fire going, he puts two lonely pieces of hamburger meat on top, to cook - only two.
Character mistake: As the movie begins, a book opens up with various fairy tell things written in it. The name Cinderella is misspelled "Cincerella" on the second page, but is spelled correctly on the first page. It is also apparent that the second page just has some of the same text as on the first page. (00:00:20)
Character mistake: When Barb introduces herself to Flint, Steve calls her a monkey, and she corrects him saying that she's an "Orangutang", pronouncing the G at the end. But the correct word is Orangutan, with no G sound. Barb would surely know this, as a genius ape.
Character mistake: When Sheriff Flemings arrives at the gas station murder scene, Deputy Baldridge is already there taking photographs. The pair exchange a few words and Baldridge says he can't find the victims body. The pair then look up to see three of the flying monkeys noisily eating Mr Sites corpse on the roof of the gas station. Apparently Baldridge didn't notice this the whole time he was there. (01:03:19)
Character mistake: When Billy is telling Diana about Sophie and who she chose, Diana asks if Paddy knew about that and Billy says no. Only problem is that earlier, Paddy told Diana that Sophie picked him, showing that he didn't know the truth, so Diana should've known that already.
Character mistake: At the end of the fight when the Channel 9 news crew shows up, Jack Lime says that they're outnumbered 3 to 1. This doesn't make any sense. Even if he's talking about the entire fight his math is off. If he's talking about who's in their group it seems to be about 9 people on Jack Lime's team, and 8 on Ron/Wes' team.
Suggested correction: There's a shot of the group when Wes says his line about his news teams emptying their gas tanks and you can count 12 people on Jack's team (there's a total of 20 people in the shot and 8 aren't on Jack's team). Jack is only talking about 12 to 4 against Wes' team, not 12 against both teams.
