Factual error: Morse code is supposedly being transmitted by the blinking street lights. They supposedly spell "For 3veryth5h1ng that 7iv3s is holy." I know Morse code. It was just a random scattering of letters. (01:00:05)
Revealing mistake: DEA Agent Rick Bowden was already seated "in the best position" before knowing where Ross would sit in the SF library. Chris Tarbell already had a surveillance camera behind the seat Ross chose, giving him a clear view of Ross, also before knowing where Ross was going to sit. Even if there were cameras in other positions, the DEA Agent and Chris Tarbell being at the right spots in advance was too coincidental to be by chance alone. (00:02:09 - 00:02:30)
Continuity mistake: When Grandma calls, teen Emily's attention while dining, her hand rests on her cheek. A shot later, it's lowered. (00:04:56)
Revealing mistake: During one of the chase scenes, an SUV hits a rock barrier and flips over landing on its top. The car spins around, and we see that it is empty. The driver then climbs out as if he was just in the vehicle.
Revealing mistake: When "Snowball" is sleeping on Lena's bed, it is obviously a "stuffed double" (stand-in). Snowball is usually partially hidden behind the dog (so breathing doesn't need to be shown/mimicked). The failure of Snowball to make even a slight movement is a giveaway (e.g, no ear movement when Lena starts talking), but even the stuffed lion, in itself, is not a very good replica - it simply looks fake. (00:33:44 - 00:48:20)
Continuity mistake: The bull horns and skull attached to the front of Doug's SUV were much larger on his way to the site than when he pulled up to the meeting spot. Initially, the horns spanned past the low beams, but were some distance from the low beams on each side when he arrived. The overall size of the skull was noticeably smaller and looked less menacing. (00:20:03 - 00:20:35)
Other mistake: When Zoe Levenson first looks out the window from the spaceship, the earth is from the bottom moving towards the top, this is opposite to the ship spinning direction, which can be determined by the direction of the gravity. (00:12:50)
Continuity mistake: Helen's slipper is at about a 45° angle toward the right of the screen when Miss Willoughby finds it. When Detective Jimmy shines his flashlight on the slipper, it is facing the opposite direction. The second time Jimmy shines the flashlight, the slipper is at a steeper angle. (01:00:33)
Factual error: At the end of the film, Hellfire Jack returns the toy soldier to the son of the late William Hawkins in 1917. Hawkins son is shown taking it upstairs and placing it in front of a photo of his father, in between two medals. These are the British War and Victory Medals - these did not exist until 1919, and in most cases were not even issued until the 1920's.
Factual error: During the escape from the farmers market a red London bus is in the background. Those busses aren't used in Gloucester.
Character mistake: Detective King (?) told Mikey, "You're on probation. You got no rights." King knew Mikey had been in prison, so should have said, "You're on parole" (not probation). Although a layperson might use probation and parole interchangeably, an employee in the criminal justice system (such as a detective) should know the differences between the terms and use the right one. A parolee is given an early, conditional release from prison and has fewer "rights" than a probationer. (00:47:10)
Revealing mistake: The possessed "Helen" that Fr Daniel threw to the ground by grabbing the back of her hair landed like a stuffed doll, not person. The "body" was mostly padding and the fake "Helen" kind of bounced or teetered after hitting the ground. Also, her arms stayed hidden in front of her whereas a real person would be stretching out or moving arms to try to land as safely as possible. (00:21:35)
Revealing mistake: The Giles brother who got "hung" when he fell after getting shot by MacMasters can be seen moving his body (mostly arms). (00:04:06)
Audio problem: When Charles knocked on the man's door to offer storm repairs, the sounds didn't match; they were slightly delayed, with the last knocking sound coming after Charles stopped knocking and lowered his hand.
Continuity mistake: The door had multiple small rectangular glass panes enclosed in wood frames, but the glass pane that Alan Schaefer's head/body went through was larger and no wood frames were visible. (00:40:28)
Revealing mistake: Based on the size of the dinosaur's back shown behind the 6' high cement enclosure, there is not enough room for the rest of the dinosaur's tail and the enclosure is not high enough to accommodate its neck and head. (00:16:29)
Continuity mistake: The dead rabbit was thrown onto its left side with its back almost parallel to the table's edge (width) and its nose/head almost in the corner. There was a bowl of several brown eggs several inches away from the rabbit's stomach. When the camera shifts, the rabbit's head has shifted at an angle away from the corner, its rear feet are slightly hanging over the table's edge (length), the bowl of eggs is touching the rabbit's stomach, and the eggs are piled on the opposite side of the bowl. (00:05:35)
Other mistake: Jane's top includes a scarf that is wrapped around her neck a few times. She starts to remove the scarf by unwrapping it clockwise. When the camera shifts, and she resumes unwrapping the scarf, she goes counterclockwise. (00:20:55)
Revealing mistake: There's no doubt that Joey and his mother were not real kangaroos, but there wasn't even an attempt to make them look at least semi-real with animatronics or better CGI. The kangaroos' appearances were more along the line of what would be expected in a cartoon or all-animated movie. (00:01:00)
Other mistake: In a voice over, Casi said, " I am a public defender. And there are only 15,000 of me for the 10.5 million people who were arrested last year in America." The statistics may not be accurate (the FBI's UCR lists an estimated 10,085,207 arrests in 2019), but it is his general statement that is misleading. Not all arrestees will be represented by a public defender - many will hire private defense attorneys. The inference of a 1,000 caseload per year exaggerates the actual of 50-590. (00:01:09)
