[SPOILERS for the Ghostbusters reboot ahead.]

After months of heated internet debate, Paul Feig’s Ghostbusters reboot is headed to U.S. theaters this Friday. The early reviews have arrived, and are a lot more positive than many expected. Producer Amy Pascal is already so confident in the film’s chances at the box office that she’s openly discussing the possibly “endless” franchise it might spawn.

Of course, before sequels can happen, the Ghostbusters reboot needs to be a success. Any moviegoers preparing to make the trip to their local theaters to see Ghostbusters this weekend are hereby advised to remain seated while the credits roll, as a post-credits scene will then appear to offer one last joke.

For those not worried about getting the joke spoiled in advance, Ghostbusters’ post-credits scene features the victorious team of unlikely heroes hard at work in a newly-built lab. Patty Tolan (Leslie Jones) is seen listening to a tape player referenced earlier in the film as having been involved with an oft-reported paranormal occurrence known as electronic voice phenomena (commonly abbreviated as E.V.P.). Excitedly, Patty turns to her colleagues and tells them she heard something. When they turn her way in response, she says she heard the word Zuul. Not knowing what that means, the other Ghostbusters shrug and are nonplussed about the whole thing.

Zuul The Gatekeeper Ghostbusters 1984 Ghostbusters Has A Post Credits Scene

Anyone who’s seen the original 1984 Ghostbusters will remember that Zuul is a supernatural creature, and serves as the gatekeeper of evil demigod Gozer. Zuul memorably possesses the body of Dana Barrett (Sigourney Weaver), and sets off to find Gozer’s keymaster Vinz Clortho, who has possessed the body of Louis Tully (Rick Moranis). When the two unite, Gozer is summoned, and naturally tries to destroy the Earth. Thankfully, the team of Venkman, Spengler, Stantz, and Zeddemore were there to save the world by way of frying up a giant marshmallow with unlicensed nuclear accelerators.

While Feig’s Ghostbusters reboot is somewhat of a remake of the original, it’s been known for many months now that while a revamped version of ol’ Stay Puft appears, the plot does not concern Gozer, Zuul, or Vinz. With that in mind, one wonders whether this Zuul mention is intended to be a hint at the plot of a potential sequel to the reboot. Then again, there’s also a chance it could just be another of the many references to the original Ivan Reitman film that Feig has chosen to sprinkle throughout the reboot, and not meant to foreshadow any grander Zuul-related aspirations. Either way, the scene will likely make for some good post-screening discussion fodder.
