There are 999 ghosts inside Disneyland’s Haunted Mansion (and always room for one more), but some of them are breakout stars. How well do you know your favorite haunts?

Ghost Host: The basso profundo voice of Paul Frees, known as the “Man of a Thousand Voices,” guides guests through the tour of the Haunted Mansion. The Ghost Host is not the owner of the mansion, but rather a high-ranking servant. In promotional material from the 1969 opening of the attraction, the Ghost Host was called the “majordomo of the Mansion’s skeleton staff.” It is believed he is the body hanging from the beam inside the stretching room of the mansion.

Master Gracey: The name of the master of the house is a tribute to Yale Gracey, a Disney Imagineer who worked on ‘Pinnochio‘ and other Disney animation projects as well as the design of many of the Haunted Mansion’s ghostly effects. A Gracey tombstone was one of the original eight located at Haunted Mansion, but it was taken out in the 1970s. Master Gracey is depicted in a changing portrait in the Haunted Mansion hallway.

Coffin man: Voiced by Xavier Atencio, a Disney animator until 1965, then an Imagineer until he retired in 1984, the coffin man cries for help. The voice was originally recorded by another actor, who made him sound more like a monster than a feeble, old man. X, as he is known, also wrote the lyrics for the song heard in the attraction, “Grim Grinning Ghosts.” He also wrote the lyrics for the song heard in Pirates of the Caribbean.

Madame Leota: Her ghostly head appears in the crystal ball, and she summons spirits to materialize. Her face is Leota Toombs, a Disney Imagineer. Her voice is Eleanor Audley, an actress in the television show “Green Acres.” In 2005, Madame Leota’s “Necronomicon: Book of the Dead” was placed in the seance room at the Haunted Mansion. The page displayed is 1313, an inside reference to Disneyland’s address on Harbor Blvd.

The Organist: The Organist plays a pipe organ with skulls coming out of the pipes. The organ was a prop used in “20,000 Leagues Under the Sea.” The music – “Grim Grinning Ghosts” – is actually played by William Sabransky, it was composed by long time Disney composer Buddy Baker.

The Bride (Constance Hatchaway): Her image has been altered several times. The sound of her beating heart survived all the changes. In 2006, Disneyland revealed her backstory: She was married five times and murdered each of her husbands. She is one of the portraits in the stretching room, holding a rose and sitting on the tombstone of her husband. The ghostly voice heard from her is from vocal actress Kat Cressida.

George Hightower: Legend has it that George Hightower of Newport Beach married Constance Hatchaway in 1877. Hightower, at one time, was the owner of the Gracey Mansion. In George’s wedding photo, he is rumored to be portrayed by long time Disney Imagineer Rick Rothschild.

Uncle Theodore: One of the singing marble busts, Uncle Theodore (second from left) is voiced by Thurl Ravenscroft, also known for singing “You’re a Mean One, Mr. Grinch” in “How the Grinch Stole Christmas.” This bust is often mistaken for Walt Disney’s image. He sings in the Pirates of the Caribbean ride and The Enchanted Tiki Room. Fans of the Country Bear Jamboree will remember his as “Buff,” the buffalo head hanging on the wall.

Hatbox Ghost: An original Haunted Mansion character, the Hatbox Ghost was removed when the special effect didn’t work (his head was supposed to disappear off his head and re-appear in the hatbox he was holding in his hand). But the Hatbox Ghost made his triumphant return in 2015.

Stretch room portraits: 1) Constance Hatchaway and George Hightower: She murdered her fifth husband. 2) Alexander Nitrokoff: He stands on a keg of dynamite. 3) Three men in quicksand: In Disney comics, they are known as gamblers Hobbs, Big Hobbs and Skinny Hobbs. 4) It could be the image of Sally Slater, about to be eaten by an alligator. The poetess Prudence Pock, whose tombstone says she died from writer’s block, has a poem that says “In the swamp, poor Sally Slater was eaten by an alligator.” It is not known if the subject of the poem and the portrait in the stretching room are the same person.
