Other mistake: Succinylcholine paralyses you for about 10 minutes; in the movie it lasts way longer, and the bad guys were planning to use it instead of ropes and cuffs. It would have bought them a really short time, surely insufficient to make their planned escape to Mexico, while tying them up with just about anything (zip ties, scotch tape) would have given them potentially hours.
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: Anna's birthday is in January, making her an Aquarius or Capricorn. Yet she's shown looking up her horoscope under Taurus which is for April-May.
Other mistake: Spoiler alert! At the end, when the sniper shoots the killer, Eve says he is 800 yards away, but within the next 30 seconds he appears at the scene. (01:22:02 - 01:22:32)
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 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.
