Melissa McCarthy, who was already in talks for one of the leads, has signed on for the Paul Feig-directed reboot, and Sony is now negotiating with Kristen Wiig as well as Saturday Night Live players Leslie Jones and Kate McKinnon, The Hollywood Reporter has learned.

Negotiations are ongoing, but the quartet are expected to sign on as the specter-seeking, poltergeist-punishing, phantom-phollowing foursome in the reboot, which is eyeing a summer shoot in New York.

McCarthy and Wiig have worked with Feig before, both breaking out in the director’s Bridesmaids.

Jones, who is currently onscreen in Chris Rock’s Top Five, joined SNL early last year and this fall was promoted to feature player status.

McKinnon has been on SNL since 2012 and last year was nominated for an Emmy for her work.

The film is set for release on July 22, 2016, Feig said on Twitter.

The Ghostbusters reboot has endured a long development process. Original director Ivan Reitman was on board to return, but while original castmembers Dan Aykroyd, Harold Ramis and Ernie Hudson had agreed to reprise their characters, Bill Murray proved elusive. Reitman then bowed out of the project when Ramis passed away last year. Following Reitman's departure, Feig was approached to direct and reconceived the project as a reboot starring an all-female cast.

Wiig is repped by UTA, Odenkirk Provissiero Entertainment and Jackoway Tyerman. Jones is repped by APA and Integral Entertainment, while McKinnon is repped by UTA and Principato Young.
