The cast of the Ghostbusters reboot sticks together both on and off the set.
On Saturday night, the film’s stars, which included Melissa McCarthy, Kristen Wiig, Leslie Jones, and Kate McKinnon, partied it up at the Bristol at the Four Seasons Hotel Boston. They were joined by their costars Neil Casey and Cecily Strong, director Paul Feig, as well as several members of the film’s production staff.
The group first grabbed a bite to eat on the lounge’s plush couches, and then moved toward the back of the room for more privacy, where they hung out until the wee hours of the morning. An upbeat Kristen Wiig, who was celebrating her 42nd birthday, was the last to arrive, and ran in to join her cast mates.
“There had to be 20 people there,” one onlooker told PEOPLE. “Everyone left at about 2 a.m.”
Several members of the cast and crew were also spotted partying at the Hard Rock Cafe on Friday night. But the group has primarily been wrapping up their busy shooting schedule, which took them from a secluded soundstage outside of the city to Boston Latin Academy this week.
The most exciting sneak peek? The new cast’s tan-and-orange Ghostbusters jumpsuits – complete with combat boots and goggles.
The movie, which also stars Chris Hemsworth, is set to hit theaters next July.
