Continuity mistake: When Manhattan starts to freeze, the car speeds through the streets with Callie and Phoebe in the copilot's seat. In the close-ups, one can see that the place is empty. In some shots, there's a shadow of a bulky object, maybe a dummy of some sort or the driver, but it's definitely not the two actors.
Continuity mistake: When the Ghostbusters win the final battle and face the Mayor, Winston's hand is on his shoulder or not, depending on the shot. This swaps back and forth.
Continuity mistake: After the car makes a U-turn, Callie's arm is not resting on the seat. A shot later, it is. (00:05:51)
Revealing mistake: When Gary is being interviewed at the end, Slimer and the Dragon fly over them and away. However, Gary keeps staring at the entrance door; seemingly, the cue didn't work here. A shot later, from a different angle, he is suddenly looking ahead.
Continuity mistake: After the car stops near City Hall Park, its position differs completely between the first and second shot, plus dark skid marks suddenly appear, despite the car not moving.
Visible crew/equipment: When the car comes to a stop next to City Hall Park, there's a crowd of bystanders in the back watching the filming.
Continuity mistake: While chasing the dragon, the car makes a left turn, and skid marks from previous takes are visible on the road. (00:06:24)
Continuity mistake: When the movie starts, the car is packed with people. When it skids and makes the U-turn, there's just the driver.
