The voice of Madame Leota was performed by Eleanor Audley who also voiced Maleficent and Lady Tremaine.
The Hatbox Ghost originally appeared when the Mansion first opened but was taken out due to the fact that sometimes had two heads, and not upholding . the Disney magic. Hatty made is comeback debut back into the attraction for Disneyland Resorts 60th anniversary in 2015.
Since 2001 Jack Skellington has taken over the attraction every Christmas as part of Haunted Mansion Holiday. Someone purchased a personalized tombstone inside the Mansion in 2004 spending $37,400. Happy Birthday Haunted Mansion and of course all 999 ghosts that live there!
