Back in June, just before filming got under way on Sony's long-awaited Ghostbusters reboot, director Paul Feig sent out a photo of himself playing with a cup of green slime, hinting that the iconic ghost Slimer will return. Then in November, a rumor circulated that this beloved green ghost will actually talk, with The Simpsons voice actor Dan Castellaneta giving him life. Paul Feig shut that casting tidbit down, but he refused to confirm whether or not Slimer is part of the movie though there were multiple reports of Slimer scenes being filmed. Earlier today, Ghostbusters star Michael K. Williams finally let the cat out of the bag, confirming that he did have a scene with Slimer.

"I'm not going to lie, working with Melissa (McCarthy), and Kristen (Wiig), and Kate (McKinnon), was really dope. But I got to work with Slimer, dude. Like Slimer!!! I'm in a scene with Slimer! I'm a huge Ghostbusters fan and it was a dream come true."

While we've heard plenty of details about the four main characters, Erin Gilbert (Kristen Wiig), Abby Yates (Melissa McCarthy), Jillian Holtzman (Kate McKinnon) and Patty Tolan (Leslie Jones), there's very little we know about the rest of the roles. Chris Hemsworth plays the Ghostbusters secretary Kevin, who may or may not get possessed by a ghost, as teased by LEGO toy set photos, and Andy Garcia is playing the mayor of New York City. Michael K. Williams revealed in this new interview that he plays an FBI agent working for the mayor, while praising the four female leads.

"I play the FBI agent who works for the mayor. Our whole thing is, we're going to tell the people it was a flash in the sky and 'Run along little women with your ghosts, we got this.' That was a dream job. They're at the top of their game, man. I had the pleasure of working with Kristen Wiig and Kate McKinnon on a show on IFC called The Spoils Before Dying. So, I had a relationship with them already. Leslie Jones, you meet her once, you feel you've known her your whole life. She penetrates any walls or any barriers you may have, she goes right through that, right to your heart chakra. And Melissa, she's just a gem. I have so much respect for these ladies because it's hard on women in comedy. She's doing it and she's bringing in other women she thinks is just as equally talented as her. I've got a lot of respect for them."

There is also very little we know about characters played by Matt Walsh, Pat Kiernan and Neil Casey, but hopefully we'll get our first glimpse of them, and the rest of the cast, very soon. Earlier this month, Sony released a preview that revealed the first trailer will debut exactly one week from today, on Thursday, March 3. Do you think we'll get to see Slimer in this first footage? Let us know what you think, and stay tuned for more on Ghostbusters.
