Lots of celebrities couldn’t pass up an opportunity to dress up in their spookiest (or silliest) get-ups this year. Whether it was Dorothy from “Wizard of Oz,” Shrek or their celebrity mentor, the stars weren’t afraid to get in the Halloween spirit.

Neil Patrick Harris, his husband David Burtka and their eight-year-old twins Gideon Scott and Harper Grace always go full throttle for Halloween. This year was no different as the family set up a Halloween photo shoot dressed as the ghosts on The Haunted Mansion ride at Disney World and Disneyland.
