Dressed in full costume, the cast of the upcoming “Ghostbusters” reboot visited patients at Boston’s Tufts Medical Center Saturday.

According to a tweet from the hospital’s Twitter account, Melissa McCarthy, Kate McKinnon, Kristen Wiig and Leslie Jones all stopped by to spend some time with patients and take photos.

“Ghostbusters” has been filming in Boston for the past month.

"They were a true delight to have today," Brooke Hynes, vice president of public affairs and communications for Tufts Medical Center, told WCVB. "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. We cannot thank them enough for the happiness and excitement they created."
