Revealing mistake: The Ghostbusters' containment unit explodes with a sinister beam that blasts through the rooftop. In the shot with the camera at street level showing New Yorkers running scared, you can see a blatant light 'halo' around one of them as by-product from the optical effect. (01:08:00)

Continuity mistake: When the heros arrive at Dana's building, they're saluted by a crowd. If you pay close attention, you'll see the same extra in two different positions (he's the young - and very "happy" - guy wearing a grey suit and a purple tie). (01:19:30)

Trivia: After the containment unit explodes, adult film star Ron Jeremy can be seen among the crowd witnessing the chaos, on the left side of the screen behind a blue police barrier.

Continuity mistake: When Dana opens the door of her refrigerator and sees the temple with a terror dog, the shelf has a bottle with a green cap and a jar with a white lid at the end of it, but when Dana slams the refrigerator after the dog says "Zuul!", both items have disappeared. (00:20:00)

Continuity mistake: When the hotel manager refuses to pay the bill after the Ghostbusters capture the green ghost (Slimer), you can see he is putting his handkerchief into his top pocket with his left hand, but in the very next shot he can be seen putting the handkerchief in the pocket with both hands. (00:38:50)

Continuity mistake: After Louis asks if anybody wants to play Parcheesi at his party, there is a lady sporting a red vest behind him, standing in front of a wall with framed photos. Two shots later, she's standing in front of the kitchen next to a bespectacled man. The very next shot, she's teleported back to where she was initially, in front of the wall. (00:53:25)

Continuity mistake: The Stay Puft Marshmallow Man has a red bow tie on as he walks down the streets of New York, which disappears in one shot as the Ghostbusters fire at him. (01:30:45 - 01:32:05)

Revealing mistake: A shot from above Dana Barret's apartment, from just above a statue looking down on the road below: The statue in the foreground is partially transparent. We can see the double yellow line on the street go straight through one of the statue's upper fangs, and one of the white lane dividers going through the statue's lower jaw. Viewed on Bluray disc. (00:16:50)

Continuity mistake: At the Lincoln Center (that place Dana's orchestra plays at) the nerd with her has his case and they're leaving when Peter is there. Nerd-boy goes off to the side and waits. When they start off again, his case pops back and forth unhumanly between being carried under his arm and in his hand between long and close shots about 3 times. (00:44:34)

Continuity mistake: When Dana returns to her apartment (the first time we see her do so) she is carrying a bag of groceries. The contents at the top of the grocery bag change with each shot: one time celery, then bread, then eggs, etc. (00:17:00)

Continuity mistake: The large blue book that Peter drops on the table to startle Egon disappears off the table in the next shot. (00:07:10)

Trivia: In the opening scene in New York Public Library, the librarian walks down the reading room with her trolley full of books and a man appears and walks across the screen. This man is the film's associate producer, Joe Medjuck. (00:00:55)
