When director Paul Feig's all-female Ghostbusters reboot was first announced, there was speculation that this project would not have any connection to the original Ghostbusters franchise. It seems that is not the case now, with a new Boston Herald report revealing the beloved green ghost Slimer will make an appearance, alongside stars Kristen Wiig, Melissa McCarthy, Leslie Jones and Kate McKinnon. Yesterday, we also reported that Kristen Wiig and Melissa McCarthy's characters have written a book claiming ghosts are real, setting up the main storyline of this remake. Today, we have more details on these two leads and what they're actually up to.

Our report from yesterday revealed that, years after writing the book, Kristen Wiig landed a prestigious teaching job at Columbia University. But her academic career comes to a screeching halt after word of her old book starts to spread across the campus. Pair this news with rumored details that surfaced back in January, it seems Kristen Wiig is playing Erin Gabler, who, according to the January report, is "an academic on the tenure track at Columbia." Melissa McCarthy is likely playing Abby Bergman, who co-wrote the book with Erin. She now works as a professional ghost hunter with Jillian. And there is Patty, an MTA employee who discovers the main ghost, rounding out the new Ghostbusters cast. Kristen Wiig's Erin Gabler reunites with Abby Bergman after getting booted from her teaching job, hinting that there may have been a falling out years ago. It still isn't known which of the two other characters Leslie Jones and Kate McKinnon are playing.

As far as Slimer goes, director Paul Feig essentially confirmed his presence in the Ghostbusters reboot with a photo he posted on his Twitter account yesterday, where the director is seen handling some of the green slime, along with the hashtag #slimetimestartstomorrow. With production currently under way, hopefully we'll get to see photos from the set very soon. In the meantime, take a look at Paul Feig's photo below, and stay tuned for more on Ghostbusters.
