Other mistake: When Walter Farris drives up in his DEA pickup, it has California plates and not federal GSA plates.
Other mistake: When removing the car from the penthouse the guys decide to use the crane portion of the window cleaner's lift. The basket disappears without trace, what did they supposedly do with it?
Other mistake: When the evil warlock breaks his way out of the condemned house, he uses explosives to escape, but for some odd reason, the door is the only thing affected by the explosion.
Other mistake: Towards the end during the last fight with Zeus, Atom is following Charlie as a mirror - when Charlie moves his right hand Atom moves its left, etc.. At one point in the last round Charlie jumps and punches with his right hand, but Atom hits Zeus with its right too.
Other mistake: Just as the preacher finishes stitching up Jake's wound, a shot rings out from the street, and everyone goes outside to find Percy Dollarhyde drunk and shooting up the town. Percy is right-handed but holsters his 6-shooter revolver on the left, and this appears to be his only sidearm. Even if he did carry another 6-shooter, that wouldn't explain how he fires 13 shots in this scene without reloading.
Other mistake: At the beginning of the trip we see close-ups of the passports of the three girls being stamped. The date is 19 Jun 2010. During the climax of the movie Emma's boyfriend puts a copy of "Le Parisien" on the counter, and the date there is Jun 10 2010. (00:12:00 - 01:26:20)
Other mistake: At the beginning of the thrill race, Judy announces that it is Tuesday, July 7th. If July 7th was on a Tuesday, August 4th (the day Rocky performs in the circus) would also be on a Tuesday. However, the fact that Judy and Stink went to a bigfoot meeting (and then had a stake out) the day before they chased bigfoot, found Mr. Todd, and went to the circus suggests that August 4th was actually a Wednesday, not a Tuesday, because Zeke says at the beginning that bigfoot meetings are on Tuesdays.
Other mistake: Between the freeway battle scene and the convenience store scene; there's a transition shot where you can see the characters walking through a bombed out LA with the alien aircraft flying above. If you pay attention to them, instead of following the camera, at the end of the shot you will see them all stop moving mid-stride while everything else in the shot continues to move.
Other mistake: In the first scene, Liz and Martin are driven in a taxi from the airport. The driver is on his mobile phone. The subtitles say that he is speaking German, however in fact he is speaking Turkish.
Other mistake: When Bishop kills the arms dealer while Steve McKenna looks on, he stands behind the guy and in one quick motion, rips off the belt cleanly from the guy's waist, then he strangles him with it. There is no way you could yank the belt off like that if it were buckled. And even then, the buckle is certain to snag or rip one or more belt loops before you can pull it off.
Other mistake: When the TV reporter is talking about the men in green being killed, she says dead bodies were found all through the city, at night. However she was reporting on the 7 bodies found (with the appropriate graphic). According to the newspaper, the 7 bodies were found by police in the morning, in one dumpster. Plus, we know when a thug killed a man in green he or she brought the body in, so they weren't found throughout the city. (And she wasn't reporting on bystanders being killed since she mentions they were all wearing green).
