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: At the beginning, the arrival board has the cities listed in alphabetical order, but "San Francisco" comes after "San Jose" when it should come before 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: In the hospital, Barrett had his right arm in a sling and his lower left leg in a cast. When the police/ detectives were trying to find Barrett, one detective said Barrett could not have driven himself somewhere because he had "a cast on his leg." The cast was on the left leg, so Barrett could have driven using his right leg, as usual. Maybe he couldn't have driven with a cast on his right arm, but the detective gave the wrong location of the leg cast. (00:50:30 - 01:13:45)
Other mistake: The protagonist uses his belt to temporarily fix the movie projector. He has to keep his pants on with his hands, but that's only until he has to grab an object and the pants do drop. Then he is still belt-less but the gag ran its course and his pants are not falling off anymore, once was enough.
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: In the scene where Margaret is wearing a bright-blue dress and a woman is sewing a button onto it while about six men stand around and wait, the woman finishes sewing the button on, but keeps on going, even though it's fixed. The whole thing takes ten times longer than it should.
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: As Johnny looks down on the wrecked car after defeating the devil, we see a blank brake disk without a wheel on. I guess it would theoretically be possible for all five lug nuts to rip clean off during an accident and leave the brake disk bare and exposed. But then the threads in the disc would still contain the shorn-off remnants of the lug nuts, instead of being empty. (01:23:00)
Other mistake: A colleague approaches Ben, picks up a newspaper, and tries to pronounce Volkskrant. Ben gives the correct pronunciation, tells him it's a Dutch newspaper. However, the top of the newspaper is visible and says Trouw, a different Dutch newspaper. (00:40:00 - 00:43:00)
