Ever wonder how movie ghosts are made? It’s 2016, and it turns out to get an audience legitimately spooked, it takes some pretty serious scare tactics.

In a recent interview with The Hollywood Reporter, VFX supervisor at Sony Pictures Dreamworks Pete Travers discussed the process of bringing Slimer, the Stay Puft Marshmallow Man, and an army of new ghosts to life with a modern, realistic look for the new Ghostbusters movie.

Travers told THR, “Obviously there’s been a lot of advancements in VFX. Paul (Feig) was a fan of the original Ghostbusters and he was hopeful, as much as possible, to have the ‘real’ ghosts on set with the actors. We worked closely with costume and production design, and stunts to make that happen.”

VFX Team Iloura created a video to illustrate the breakdown of how the spooktacular ghosts were created.

Many of the ghosts were actors dressed in period costumes with LED lights sewn into their outfits. The ghost to make the first appearance in the reboot is Gertrude, played by Bess Rous. Her haunting hover was created with moving platforms and wires, and LED lights sewn into her dress. “This way we had the light reacting to the environment and the actors and the ghost herself. And the Ghostbusters could react to the ghost and not act against a tennis ball,” Travers told THR.

Slimer and the Stay Puft Man, on the other hand, weren’t created with actors. The OG Slimer from the ’80s film was actually a puppet, and while the same puppet was used for lighting and reference for the new version, Slimer and the Stay Puft Man were completely CG for the film.

The hard work and innovative ideas from the special effects team definitely paid off, because as often as there was laughter from the audience, there was also some pretty genuine fright (or was that just us? We were legit spooked). Because seriously, these ghosts were hella scary, guys.
