Other mistake: The Angels do a clean sweep of all the bad guys, tie them up and put their heads in bags. It's kind of a plot point that they have all the baddies perfectly packed up and ready for delivery. However when Bosley makes his entrance, there's a guy in the elevator he leaves behind, the door closes and nobody 'bags' and/or ties him up. He's just unaccounted for. (00:05:10)
Other mistake: Hannah's bag (purse) never reappeared and after the first day when she said it contained her license and phone, she never asked for them again! What 17-18 year-old would not be concerned about her driver's license or cell phone? The next morning at the playground across from the school, Lily even said, "Give us the bag or I will hurt you." Hannah was driving without a license.
Other mistake: It was pouring rain when Denny got home in a taxi, but he somehow managed to walk from the curb, up the sidewalk, and into the front door without getting his jacket or face wet. His hair might have got a little wet but, if so, it quickly dried. (00:26:10)
Other mistake: The gun choreography in the fight at the Hound Dog just sucks. Nevada picks up the now zombiefied Albuquerque's gun, a Mini Draco AK with a (at most) a 10 round magazine, can barely hold it up but longarms it like a handgun and *brrr* fires at about double the guns actual fire rate. Infinite ammo, zero recoil (with a small stature woman firing 7.62x39 with one hand no stock) and the entire time she's shooting, the gun is pointing right at Tallahassee's head. (01:01:55)
Other mistake: When Jack and Rocky get on Ed Sheeran's plane, they are carrying 2 guitars. After the Moscow concert, before the 'song challenge', Ed says Jack wrote 'Back in the USSR' on a 3 hr plane flight with no guitar on the way to the show. (00:37:38 - 00:38:38)
Other mistake: When the characters go to the Himalayas, the whole time, like for 20 mins, including the confrontation scene, they are all wearing casual, short-sleeved shirts. You can see Mr. Burnish's henchmen wearing winter clothing, while the main characters don't freeze to death. They only start getting cold after a long time.
Other mistake: When Jenny and her friends are in the grocery store, they grab string cheese from a shelf that isn't refrigerated - it is just a random shelf and the cheese just stands out as so wrong.
Other mistake: When Ki-jung is making the fake diploma, the date she uses is June 16, 2018, indicating the movie takes place after then. In a later scene, when Yeon-kyo texts Ki-taek to meet in the sauna, the date on the text is June 12, despite being a later date. (00:11:20 - 00:44:40)
Other mistake: When Tom checks his phone and tells Charlotte that the president is looking for her, his phone is upside down. (01:30:00)
Other mistake: Nick Spitz shows the flight attendant his shield to gain access to the first class cabin. The shield is an NYPD patrolman shield. However, Nick is later identified by another character as an NYPD sergeant. (01:24:10)
