All That's 3D
Is Not Holography:
Disney World's Haunted House
By Charles Otis Sweezey
Associate Professor Department of Theater and Dance Southern Illinois University
Ghosts are fascinating creatures of the supernatural. They float thought
the air, appearing and vanishing, possessing a translucent quality as if
made of vapor. Usually inhabiting old houses and grave yards, their more
recent residence is a building in Disney
World appropriately called the "Haunted Mansion". How these
ghosts came to be has been a long-kept secret of Disney World. Many people
believe them to be elaborate holograms, for they are three-dimensional,
appear to be translucent, and have the characteristics of a hologram. This,
however, is a misconception which is furthered by the fact that few people
have a real understanding of holography.
Disney World is also known as "The Magic Kingdom," and like a
true magician, it has never revealed the mechanics of the ghosts, knowing
that an illusion is never as effective once the trick is discovered. I
had heard many people insist that these ghosts are holograms; others stated
that they were created by lasers. What bothered me about their beliefs is
that the art of holography is still in its infancy. It would require a great
deal of time and money before such effects could be possible and still,
Disney's expectations would not be satisfied it was this bafflement that
enticed me to travel to Disney World to discover how the ghosts really haunt
Upon entering the Mansion for the first time, I was greeted by an eerie
presence. The rooms are dark and covered with dust and cobwebs. A cold,
clammy draft blew across my shoulder. The journey proceeded through the
house on a "Doom Buggy" which is designed to turn around, tilt
forward and backward, and turn one's attention only in the direction desired
for one to observe the full effect of the attraction. Like a skilled magician,
Disney has total control, having one see only what he wishes, and not observe
what one shouldn't. The ride through the Mansion in quite effective and
one of the most enjoyable and popular attractions at Disney World. The total
effect is impressive. After several journeys, I learned what to expect,
and began to decipher how the ghosts are manufactured. It is readily apparent
that they are not produced by holography, but by an elaborate combination
of illusionary effects, which make use of the latest in technology mixed
with nineteenth century magic. The entire production is controlled by a
sophisticated computer system.
The "talking heads" present an interesting illusion. "Madam
Leota's" head appears in a crystal ball and chants a message to the
visitors. Near the end of the journey there is a group of singing marble
busts. At the exit, a small doll-like figure, "Little Leota",
bids farewell and extends a "ghoulish" invitation to come back
again. All of these apparitions are created in the same manner. The facial
features are provided by a 16mm film which is projected into a faceless
mannequin head. A closer look at "Madam Leota's" head reveals
an image on the glass of her crystal ball, caused by the projection entering
the glass just below her chin.
Other ghosts and ghouls are translucent versions of mechanized robots, similar
to ones used elsewhere in the park. As in the Hall of Presidents, the Haunted
Mansion makes use of "animatronic" figures. These figures use
an elaborate system of hydraulics and computers to make them move. In this
particular application, Disney goes a step further and uses figures which
were cast in clear plastic; only around motorized areas, as the head, are
they more opaque. The figures are dressed in sheer fabrics, and to increase
the sense of fogginess, are viewed from behind a gauze fabric. The effect
is heightened by the lighting.
The largest "ghostly" effect in the Haunted Mansion and the one
which most resembles a hologram is the illusion created in the Grand Ballroom.
Here ghosts are seen dancing, floating, and waving in a large, three story
room. The viewer observes these ghosts by looking down into the room. This
effect is modeled after a nineteenth century magic trick in which a woman
is seen in a room, and a magician aims and fires a gun at her. This illusion
is created by a special two-chambered box. A sheet of glass, set at an angle,
is situated between the rooms. When light is brought up in the first chamber,
the glass acts like a mirror and reflects the room and the woman. Changing
the lighting from the first chamber to the second, causes the glass to become
transparent, allowing the audience to view through it. Both chambers have
identically decorated rooms but only the first has the woman; by adjusting
the lights she appears and disappears.
The Haunted Mansion uses the same principle as this nineteenth century magic
trick. The "Doom Buggy" carries the viewer above the Grand Ball
Room and tilts forward so that the rider is looking down into it. The viewer
is not aware that there is a sheet of glass between him and the room. Above
and below the room and out of sight are mechanized ghosts which are moving
and dancing. By using strong lighting, the reflections of the figures appear
on the glass and the observer is tricked into thinking that there are ghosts
in the room.
Additional effects and illusions are incorporated throughout the ride. The
eerie sounds and general darkness make the rider susceptible to seeing things
that are not real. Effects like doors that "breathe" and rooms
that "stretch" create the desired mood. With all the elements
working together the viewer begins to wonder if they are not "real
ghosts" inhabiting the Haunted Mansion.
