Factual error: In the flashback of Cartman watching the Ghostbusters remake, there is a list of times for other movies playing at the theatre shown in the ticket booth. The movies listed are The Accountant, Ghostbusters, The Girl on the Train and Kevin Hart: What Now? The flashback is supposed to take place in the summer, around the time the Ghostbusters remake was released. The Ghostbusters remake was released in the US in July 2016, however the movies, The Accountant, The Girl on the Train and Kevin Hart: What Now? were not released in the US until October 2016, almost three months apart from each other.
Continuity mistake: When the agents are taking Gerald below the bridge to meet with Hillary Clinton, in the angle where Gerald says that he was set up and is not Skanthunt42, the agents grab hold of him and make their way under the bridge. As the shot ends, Gerald and the agents are about to go under the bridge, but in the next shot, they are suddenly further away from the area under the bridge. The shot cuts again and they are suddenly directly under the bridge.
