Kristen Wiig, 'Ghostbusters' co-stars pay surprise visit to hospital

BOSTON, Aug. 3 (UPI) -- Kristen Wiig and her Ghostbusters co-stars paid a surprise visit to Tufts Medical Center on Saturday.

The 41-year-old actress and castmates Melissa McCarthy, Leslie Jones and Kate McKinnon were filming in the area when they headed over in costume to visit patients at the Boston hospital. Children being treated at Tufts had put a "Who ya gonna call?" sign up in the window.

"They were a true delight to have today," hospital vice president of public affairs and communications Brooke Hynes told People magazine. "They were so kind to all the kids and their parents. They took their time in each room visiting children as young as a few months to teens."

The actresses posed for several photos, which Tufts Medical Center later shared on Facebook. "Thank you for taking the time out of filming today to put a big smile on our patients faces! #WhoYouGonnaCall #Ghostbusters," the hospital wrote.

Ghostbusters is a female-led reboot of the original 1984 film, and opens in theaters July 22, 2016. The movie is helmed by Paul Feig, who directed Wiig and McCarthy in Bridesmaids, and co-stars Neil Casey, Chris Hemsworth and Andy Garcia.
