Paul Feig is using Twitter to slowly tease his take on Ghostbusters, and after showing off everything from proton packs to their car, the director has now revealed the names of the four female leads in the movie.

From left to right in the image above, we have Patty Tolan (Leslie Jones), Abby Yates (Melissa McCarthy), Erin Gilbert (Kristen Wiig), and Jillian Holtzmann (Kate McKinnon). Should the Ghostbusters reboot prove to be a success, we’ll no doubt get very familiar with these characters as this could launch a whole new franchise.

An unofficial plot synopsis for Ghostbusters claims that Wiig and McCarthy play a pair of unheralded authors who write a book positing that ghosts are real. Flash forward a few years and Wiig lands a prestigious teaching position at Columbia U. Which is pretty sweet, until her book resurfaces and she is laughed out of academia. Wiig then reunites with McCarthy and the other two proton pack-packing phantom wranglers, and she gets some sweet revenge when ghosts invade Manhattan and she and her team have to save the world.

Ghostbusters is set to be released on July 22nd, 2016. The cast also includes Chris Hemsworth (as the team’s secretary), Andy Garcia, Michael K. Williams, Matt Walsh, and Neil Casey as the reboot’s lead villain.
