Sir Alistair Crump, later known as the Hatbox Ghost, is the main antagonist of the 2023 supernatural horror comedy film Haunted Mansion, based on the Disney Parks theme park attraction of the same name. In his characterization, he is one of the several spectral spooks sealed in the Haunted Mansion - a haunted house located in New Orleans, Louisana. He was accidentally summoned by the house's owner, William Gracey in an attempt to contact his deceased wife. He tricked Gracey into committing suicide and took up residence in the Gracey mansion, controlling other spirits that inhabited the house and tricking its residents into committing suicide. Having haunted the building for years, the Hatbox Ghost quickly joins all of the mansion's ghosts in scaring out its newest owners, a single mother called Gabbie and her young son Travis, prompting them to gather a team of ghost exterminators led by Benjamin "Ben" Matthias.
