While the New York Library exterior
and vast reading room...
:01:03
created a perfect Gothic atmosphere,
the book stacks flunked their audition.
:01:06
For "aesthetic and economic reasons,"
the producers shot these scenes...
:01:09
at the main branch
of the public library in Los Angeles.
:01:11
The final shooting script
called for more than a dozen books...
:01:14
to suddenly fly off the shelf
and land at the feet of the librarian.
:01:17
But at the last minute,
Dan Aykroyd suggested...
:01:20
this more subtle and eerie approach...
the first of 200 optical effects...
:01:23
by visual effects creator
Richard Edlund and his team.
:01:37
This next bit of ghostly mischief...
:01:40
falls in the category of a physical
effect rather than an optical effect.
:01:43
Special effects supervisor Chuck Gaspar
built a bank of card cabinets...
:01:46
rigged with air hoses
to spew the cards out on cue.
:02:01
The librarian had speaking lines
in the script, but during production...
:02:04
her lines were dropped and replaced
with screams and whimpers.
:02:07
The original script called for a "stout,
studious-Iooking girl in her late 20's."
:02:10
But Alice Drummond as a terrified,
fleeing middle-aged librarian...
:02:12
was a perfect casting decision.
:02:23
The Ghostbusters logo was refined
by artists, but Dan Aykroyd created...
:02:26
the idea for the logo when he dreamed
up the original concept of the film.
:02:29
In a departure
from motion picture tradition...
:02:31
the production credits were
withheld until the end of the film.
:02:38
In the original script, this graffiti
contained an obscene sexual reference...
:02:41
to Bill Murray's character, Venkman,
but director Ivan Reitman thought...
:02:44
that "Ghostbusters" would benefit...
creatively and economically...
:02:47
from not being particularly raunchy.
:02:50
"It has an edge to it," said Reitman,
"but it's the kind of film...
:02:53
parents are comfortable taking
their five- and six-year-olds to see."
:02:57
Harold Ramis, Dan Aykroyd's co-writer,
came up with the idea...
