'Ghostbusters' Adds Michael K. Williams, Andy Garcia, And Matt Walsh

Paul Feig's Ghostbusters has been shooting in Boston and the surrounding area for a couple weeks; Feig has even shown off some of the film's costumes on Twitter, though we have yet to see the characters all suited up. Kristen Wiig, Melissa McCarthy, Leslie Jones and Kate McKinnon are the four primary characters, and Chris Hemsworth is in the film, too, as the crew's receptionist.

Now, three more actors have been revealed as part of the Ghostbusters cast, and we've got a few details of who Michael K. Williams, Matt Walsh, and Andy Garcia will be playing. One is the new Ghostbusters mayor.

The Wrap reports on the casting. Williams, who we know and love from The Wire and Boardwalk Empire, in addition to so many other roles, will play a character named Hawkins, and Matt Walsh, who is so great as Mike McLintock on Veep, will play a character named Rourke.

And then there's Andy Garcia, who is signing on to play the Mayor of New York City. (Despite the Boston shoot, the film takes place in NYC.) So he will presumably get to play some new version of the scene in which he has the opportunity to indirectly save the lives of millions of registered voters.

In the headline for the original report, The Wrap mentions that Cecily Strong has also joined the cast, but doesn't offer any info in the report itself. And New York City's NY1 morning anchor Pat Kiernan will appear as a news anchor.

Much of the story of the film is still under wraps, but Kristen Wiig and Melissa McCarthy are rumored to play Erin Gilbert and Abby Bergman, "a pair of unheralded authors who write a book positing that ghosts are real." Kate McKinnon is said to be Gilbert's new partner, Jillian Holtzmann, while Leslie Jones plays Patty Tolan, the subway worker who stumbles across a supernatural threat that proves to be a prime motivator for the film.

"Flash forward a few years and Wiig lands a prestigious teaching position at Columbia U. Which is pretty sweet, until her book resurfaces and she is laughed out of academia. Wiig reunites with McCarthy and the other two proton pack-packing phantom wranglers, and she gets some sweet revenge when ghosts invade Manhattan and she and her team have to save the world."

Ghostbusters, written by Feig and Kate Dippold, opens on July 22, 2016.
