Artist Thom Enriquez was very involved
in developing the look of this ghost.
:31:37
Known by the public as "Slimer"...
:31:39
the name of this spook
was actually "Onionhead."
:31:46
The room service cart
was actually a motorized vehicle...
:31:49
driven from underneath by one
of Chuck Gaspar's crew members.
:31:53
Where it crashes into the wall,
the driver was removed...
:31:56
and the cart was merely
pushed into the wall.
:32:00
In the script, Harold Ramis
knocks on a hotel room door...
:32:03
and is confronted by a beautiful woman
wearing nothing but a towel.
:32:06
That scene was never shot.
:32:15
During preproduction, three large-scale
Onionheads were sculpted...
:32:18
one for smiling,
one for looking frightened...
:32:20
and one for use
in the drinking scenes.
:32:22
After the sculpting, the figures were
cast in the form of a latex suit...
:32:25
with facial movements achieved
through cable mechanisms.
:32:28
Mark Wilson wore the latex suits
and performed the major actions.
:32:31
A team of puppeteers produced the
subtle, cable-activated expressions.
:32:34
Oversized props were used
in the live-action scenes...
:32:37
so that when the ghost shots were
combined with live-action sequences...
:32:40
Onionhead would be made
to appear smaller than human-size.
:32:55
"Ectoslime" was a gooey substance
made from methylcellulose ether...
:32:58
a powdered thickening agent used in
pharmaceuticals and food products.
