Factual error: The Sheriff of the small town is wearing Sergeant stripes on her shoulder sleeves. If she was a Sheriff then no chevrons should be on her sleeves.
Factual error: The film states that the story takes place in the year 1998. Everything in the opening scenes crams in every 90's cliché imaginable to reinforce the era. However, at 1m56s into the movie, the main character is driving on the freeway and it cuts to a shot showing that he's driving behind a marked police car. Specifically, a Police Interceptor model Ford Explorer that did not hit the market until 2012. (00:01:56)
Factual error: After they get the key from the game, the lock they open is a modern Kwikset Smart Key cylinder.
Factual error: It's a hard winter everywhere is film except in the scenes that take place in Denver. In one scene when Coxman kidnaps Viking's son, there are full leaves on trees and cherry blossoms. Moments prior there's a frozen tundra shot coming into Denver.
