The villain in the 'Ghostbusters' reboot isn't a household name, but he's a fixture in the comedy community

It's not the Stay Puft marshmallow man, but it'll do.

According to Deadline, comedian Neil Casey has been cast to play the villain in Sony's "Ghostbusters" reboot.

Casey joins an already stacked comedic lineup that includes Kristen Wiig, Melissa McCarthy, Kate McKinnon, and Leslie Jones.

Details of Casey's character, Rowan, are mostly being kept under wraps.

While Casey isn't a household name just yet, it is likely you have seen him pop up in a number of places.

Casey got his start as a performer at New York's Upright Citzens Brigade (UCB). If you ever went to one of their famed Assscat 3000 shows, you would very likely have seen him perform.

Casey was a writer for "Saturday Night Live." He has also written for critically acclaimed sketch shows "Inside Amy Schumer" and "Kroll Show" on Comedy Central.

Casey has also popped up on "Broad City" and stars in the Yahoo original series "Other Space." "Other Space" was created by Paul Feig, who is directing "Ghostbusters."

"Ghostbusters" will be out in theaters in 2016.
