“Who ya gonna call...?”

For some patients at Tufts Medical Center, a phone call wasn’t even necessary because comediennes Melissa McCarthy, Kristen Wiig, and other members of the Ghostbusters cast came out on Saturday to surprise patients.

The group roamed through the hospital in full movie attire, checking under beds and doing mock scans for ghosts, as well as visiting with patients and their families, E! News reported.

A Tufts Medical Center spokeswoman said that the cast was a delight to have.

“There were so kind to all the kids and their parents,” said Brooke Hynes, VP of Public Affairs. “They took their time in each room visiting children as young as a few months to teens. We cannot thank them enough for the happiness and excitement they created.” 

For the past few weeks, filming for the movie has been occurring outside the now ghost-free hospital. Some of the kids at the Floating Hospital put a sign in the window that spelled out “Who ya gonna call?” as an art display.

The display reportedly grabbed the attention of cast and crew and ultimately led to the surprise visit.

According to reports by E!, the highly anticipated new Ghostbusters movie is set to release on June 22, 2016.
