The cast of the upcoming all-female Ghostbusters remake visited a children's hospital over the weekend.

Leslie Jones, Kate McKinnon, Kristen Wiig and Melissa McCarthy paid a visit - in costume - to the young patients at Tufts Medical Center's Floating Hospital for Children in Boston on Saturday, according to posts on social media.

""Thank you for taking the time out of filming today to put a big smile on our patients faces! ‪#‎WhoYouGonnaCall ‪#‎Ghostbusters," the facility wrote in a Facebook post.

Ghostbusters is currently filming in Boston and is scheduled to be released in July 2016. Check out some photos of the cast's visit below:
