Director Paul Feig tweeted a reply to an unofficial Twitter account of a Ghostbusters fan the official names of the characters to be portrayed by Melissa McCarthy, Kristen Wiig, Kate McKinnon and. Leslie Jones.
So Melissa McCarthy will be playing Abby Yates, Kristen Wiig is Erin Gilbert, Kat Mckinnon is probably Patty Tolan and Leslie Jones is Jillian Holtzmann.
Erin Gilbert (Wiig) and Abby Yates (McCarthy) are a pair of unheralded authors who write a book positing that ghosts are real. A few years later Gilbert lands a prestigious teaching position at Columbia University, but her book resurfaces and she is laughed out of academia. Gilbert reunites with Yates and others when ghosts invade Manhattan and she and her team have to save the world.
Ghostbusters arrives in cinemas July 2016 distributed by Columbia Pictures, local office of Sony Pictures Releasing International.
