Best crime movie other mistakes of 2017
Other mistake: After John gets his car back in the second scene, he gets chased by a motorcycle. John opens his car door to knock the biker off - as the bike flips the stunt actor/CGI model totally disappears.
Other mistake: At the end of the movie, when Cory is in Natalie's bedroom, Cory stops and looks at a picture of Natalie and his daughter wearing a high school graduation cap and gown. Cory said his daughter was only 16 when she died so she would've already been dead by the time Natalie graduated.
Other mistake: During the opening trap we see Mitch strike the blades with his chain and get yanked forward. However, despite being yanked forward he still manages to stand in line with the others which he shouldn't be able to do, as his chain was shorter due to the extra tug he received.
