"From the time we turn on our nutrona
wands to try and corner the ghost...
:34:43
Ivan wanted the scene played
as continuous action...
:34:46
so there's not a lot of directional
dialogue here...
:34:48
with people saying
what they are doing.
:34:50
You see the Onionhead
dive behind the bar.
:34:53
My character opens fire on it...
:34:55
completely destroying it."
- Harold Ramis

The destroyed walls were actually
prefabricated wall panels...
:35:15
brought to the hotel
by the film crew.
:35:18
The panels were imbedded
with pyrotechnic materials...
:35:21
that could be ignited on cue.
:35:29
This is a little bit of business
that wasn't in the script.
:35:32
Bill Murray couldn't
resist the temptation.

The colorful nutrona beam effects
were produced later...
:35:44
at Richard Edlund's
Entertainment Effects Group...
:35:46
through a variety
of animation techniques.
