Last month, the movie’s director Paul Feig announced via Twitter that the fab foursome had officially signed on to appear in a new version of the hit 1984 movie that originally starred Bill Murray, 64, Dan Aykroyd, 62, Ernie Hudson, 69 and the late Harold Ramis.

“In other news, #Ghostbusters will be hitting theaters July 22, 2016. Save the date!” Feig tweeted on Tuesday, Jan. 27 following a photo he posted of the upcoming film’s new cast.

On Sunday, Leslie, 48, and Kate, 31 — who are both current cast members on ‘Saturday Night Live’ — were joined by ‘SNL’ alumna Kristen, 41, and comedienne Melissa, 44, for the three-and-a-half hour ‘SNL 40’ special in NYC.

Kristen and Melissa previously worked together in the 2011 movie ‘Bridesmaids,’ which Feig also directed.
