[Update: Variety adds that Michael K. Williams is also in talks for a crucial role in Assassin’s Creed, one that would see him take a co-starring position opposite Michael Fassbender in the sequel.]

Filmmaker Paul Feig’s reboot Ghostbusters has been filming in Boston for a couple of weeks now, but the comedy is now adding a few more cast members. The Wrap reports that Michael K. Williams, Andy Garcia, previously rumored SNL alum Cecily Strong, and Veep standout Matt Walsh have joined the ensemble, which stars Kristen Wiig, Melissa McCarthy, Kate McKinnon, and Leslie Jones as aforementioned busters of ghosts. The most recent new cast member to be added outside the central quartet was Chris Hemsworth in a stroke of brilliant casting as the Ghostbusters’ secretary, filling the seat of Annie Potts from the original film.

This new casting isn’t as exciting as the “Hemsworth as Secretary” news (really, what is?), but The Wrap does add that Garcia is playing a powerful politician, so perhaps he’s the movie’s primary human antagonist. The Wire alum Williams is playing a character named Hawkins, while Walsh—who routinely slays as press secretary Mike McLintock on HBO’s Veep—is playing a character called Rourke.

The Ghostbusters reboot was penned by Feig’s The Heat scribe Kate Dippold and is very much a reboot, not a remake. Feig wasn’t interested in trying to recreate the roles made famous by Bill Murray and Co., nor did he want to craft a sequel that spent time acknowledging the time lapse between films. Instead he’s going the full reboot route, creating a new story that honors what came before, but isn’t beholden to the story points or original characters.

Update: And for those of you who are looking to make your new Ghostbusters Proton Packs as realistic as possible, Feig has provided new details in the following image:
