Appropriately, this week's 80's trivia question has a halloween theme about the Ghostbusters Movie:

A red circle bisected by a diagonal red stripe. Place this symbol over a cigarette, it means 'No Smoking,' place it over a clown, it means 'No Bozos.' Place it over a spook, and you've got the Ghostbusters logo. Like a team of metaphysical dog catchers, the Ghostbusters offer a service to haunted eighties New Yorkers every bit as essential as that of the exterminator: ridding your property of ghosts. But as the film progresses, the Ghostbusters discover that the ghoulish infestation of New York is much more serious than they originally thought. A portal is being opened to the netherworld, through which Gozer the Destructor will emerge to destroy the world. In the films climax, the Ghostbusters confront Gozer, who transforms from a haunting young woman into a gigantic monster that lumbers through the city streets. What form does Gozer assume in order to terrorize New York City and destroy the Ghostbusters?

Bonus Question: At one point in the film Ghostbusters, a teenage girl is seen celebrating her birthday at Central Park's Tavern on the Green. Who plays the part of this teenage girl?
