The Ghost Host is the narrator of the Haunted Mansion attractions. Contrary to popular belief and some adaptations, he is not intended to be Master Gracey.
At Disneyland and the Magic Kingdom, the Ghost Host is voiced by Paul Frees. Corey Burton provided the voice for Disneyland's seasonal Haunted Mansion Holiday and for most of his other later appearances. At Tokyo Disneyland, he is voiced by Teichiro Hori.
At Phantom Manor in Disneyland Paris, the Ghost Host's role is played by a character called The Phantom, who was voiced by Vincent Price in English, but due to legal complications with the French government requiring that the audio be in mostly French, Price's voice was eventually replaced by that of Gerard Chevalier.
The Haunted MansionThe Ghost Host is a disembodied voice and is never seen. In the Stretch Room, the Ghost Host torments guests by challenging them to find a way out of the room, which has "no windows and no doors." He then suggests, "Of course, there's always my way." The room immediately falls dark and lightning strikes above, revealing his corpse hanging from the ceiling, implying that he resorted to suicide.
Despite common fan beliefs and adaptations, the Ghost Host is not Master Gracey, but instead is the "hanged man" depicted in a portrait in the Corridor of Doors.
The shadow playing the piano in the Florida and Tokyo versions of the attraction is said to be the Ghost Host himself at the keys.
The Ghost Host, voiced by Corey Burton, provides the opening "Welcome Foolish Mortals" line. The film's Master Gracey is the man hanging in the Stretch Room, following the usual fan interpretations of the character.
Like the film, the Ghost Host and Master Gracey are the same characters, with his physical form confined to the Stretch Room. When the Mansion hits 1000 ghosts and is trapped in an alternate dimension, the corpse falls to the floor proper and finally manifests as a ghostly version of Gracey.
The Ghost Host serves as the player's guide in the Haunted Mansion mini-game.
