"Floating Hospital for Children at Tufts Medical Center patients got a huge surprise today when Ghostbusters stars Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones came to visit!" read the Facebook post. "Thank you for taking the time out of filming today to put a big smile on our patients faces! ?#‎WhoYouGonnaCall? ?#‎Ghostbusters?."

The hospital's Facebook page added the following caption about the above photo: "This sweet patient couldn't have visitors in the room when the Ghostbusters were there but wanted a photograph, so the ladies posed outside the room to get her in the shot. Very thoughtful ladies!" Additionally, Jones retweeted several photos posted by other people of the cast with patients.

A number of film stars have appeared in costume to help cheer up hospital patients this year, including Johnny Depp dressing as Jack Sparrow in Australia, along with Marvel stars Chris Evans (Captain America) and Chris Pratt (Star-Lord) donning their outfits in Seattle.

The new Ghostbusters film, which is currently shooting in Boston, hits theaters on July 22, 2016. The Facebook and Twitter posts can be seen below.
