Yesterday was a huge day in the world of Ghostbusters, as the all-female cast of Paul Feig’s reboot was at long last announced. Kristen Wiig, Melissa McCarthy and Saturday Night Live stars Kate McKinnon & Leslie Jones will be taking over the iconic roles, and news about the film is chugging right along.

Shortly after we posted that story yesterday, we learned that Sony plans on releasing their Ghostbusters reboot on July 22nd, 2016, with the New York City shoot planned for later this year. And today we’ve learned a whole lot more about the project, including character details that shed some light onto what we can expect.

The folks over at Hit Fix managed to get a hold of brief character bios for the characters each of the four ladies are playing, including their names and some information about them. This is, to date, the most info we’ve yet been provided about the film, so read on!

“Kristen Wiig is playing Erin Garber, a published author on the subject of the paranormal. Erin now works for Columbia University.

Leslie Jones is playing Abby Bergman, who co-authored the book with Garber. Since publication, the two former colleagues had a falling out and went their separate ways. Abby more actively chases ghost a la Ghost Hunters. This tension between academic investigation (Wiig’s character) and mainstream media investigation (Jones’ character) is central to the story.

Kate McKinnon is playing Abby Berman’s new partner, Jillian.

Melissa McCarthy is playing Patty, an NYC subway worker who stumbles across the main, supernatural threat in the film.”

The site also reports that Sony is hoping to nab Bill Murray for the role of Martin Hess, a man who sets out to prove that the Ghostbusters are frauds. It was Murray’s lack of interest in the project that led the film down the all-female path, so it will be interesting to see if they can get him for this iteration of it – though I’m not holding my breath.

One actor expected to be cast is Peter Dinklage, portraying the film’s main villain. It’s been reported that he’s going to be an evil spirit who will raise an army of New York’s dead, which the ladies will have to contend with. Sounds true to the spirit of the original movies, if nothing else!
