Other mistake: Based on where Carol is standing near the top of the stairs of her new apartment, more of the couch behind her should be to the left of the screen (like it is in a later shot). (00:48:10)
Other mistake: When Mike goes through Isabel's file, it says that she escaped prison on April 10, 2019. However, the scene is set on August 22 of the same year, 2019 (it says the date right there as it checks "the last 2 months" of phone calls with Dorn). Mike was shot at least 6 months before (it says "six months later" in the wedding scene, which is where he makes his reappearance after the shooting scene, possibly more time passed). Mike was shot only after Isabel got out of prison, so that's impossible. (01:24:30)
Other mistake: I don't think enough is known about the mating and birth habits of Great White Sharks to label this a factual or character mistake. Emma said, "Sharks return here each year to feed, mate, and give birth." I don't think sharks mate and give birth in the same location plus females give birth every 2-3 years. After mating (in deep water away from humans), the male and female go their separate ways and the female apparently gives birth close to the coast (shallow water) for the pups' protection. (00:03:36)
Other mistake: When Lomito was holding the little green ball with the smiley face on it, her flashlight was shining on her fingers/fingernails - all of which were long and manicured. The length of her fake fingernails - even if they did not exceed the department's policy on maximum length, such as one-fourth inch past the fingertip - probably were long enough to interfere with her ability to quickly put her finger on her pistol's trigger and shoot; the length interfered with her ability to perform her duties.

Other mistake: Alpha was standing at an angle to the senator when he shot him in the forehead, but the bullet hole was not angled as would be expected. Alpha was also holding his gun slightly upward when aiming at the senator's forehead, but the majority of the (odd-shaped) blood splatter behind him was near the back of his neck instead of higher. All blood splatter went behind the senator, but some should have been in front. (00:21:05)
Other mistake: Jung-seok's nephew accidentally drops a ball which rolls away and lands in front of a nearby bed. When he walks over to get it, he realises that the man sitting on the bed has turned into a zombie. He is shown in a contorted position, with his back lifted off the ground and is heard making painful grunting noises. The other passengers in the cabin then realise there is a zombie in the room with them. It is extremely hard to believe that none of the other passengers in the cabin would have noticed this beforehand, not even by accident. This man's body was in a completely inhuman and unrealistic position, but it's not until the nephew walks up to him where people start to notice. (00:05:25)
Other mistake: Jack took Illinois licence plate "BL 91021" off a Subaru SUV to put on the group's truck and put "V 986394" on the Subaru. Illinois truck (< 8,000 pounds) plates have the letter "B" on the middle-right side of the plate. The "BL 91021" would have too many numbers to be valid. By putting a license plate starting with "V" on the SUV - without the letter "B" on the middle-right side - the SUV would not have a truck plate like it should (and would also have too many numbers to be valid).
