Directed by: Ivan Reitman
Starring: Dan Aykroyd, Bill Murray, Sigourney Weaver, Harold Ramis, Rick Moranis, Ernie Hudson, Annie Potts
Audio problem: Running away from the 'bear', Tully shouts the humorous line; "I'm gonna to bring this up at the next tenants' meeting...there's not supposed to be any pets in the building." However, look at Rick Moranis' face; his lips are not moving and the line was dubbed over. (00:54:10)
Audio problem: When the Archbishop says "How are you, Lenny?" to the Mayor in his office, his lips don't match what he is saying. (01:15:55)
Revealing mistake: There's a scene where Dana's building is falling apart and stones and stuff are falling to the street below. One of the huge boulders bounces off a wooden police barricade in the bottom left hand corner of the screen, and then off a person. (01:29:14)
Ray Stantz: Everything was fine with our system until the power grid was shut off by dickless here.
Walter Peck: They caused an explosion!
Mayor: Is this true?
Peter Venkman: Yes, it's true. This man has no dick.
Trivia: Director Ivan Reitman performed the demonic voice of Dana/Zuul in the bedroom scene with Peter Venkman.
Question: I heard that Ron Jeremy had a walk on part in this film, does anyone know in which scene he is in?
Answer: Ron Jeremy can be seen in the crowd outside the firehouse right after the containment unit is shut off.
