When they do these live reads, are they using the final shooting script or are they using a transcript of the finished movie?
' [Reitman] was surprised when he went back and looked at the original script of the movie for Thursday night’s reading at the Los Angeles County Museum of Art.
It turns out, Murray was making it all up as he went along.
“While almost all of the dialogue in original screenplay is echoed on screen, the Venkman character is completely improvised. It’s as if Bill Murray was given a mumblecore-style essay about each scene and then permitted to say whatever he wanted as long as he got the point across,” Reitman tells EW.
“He’s like a jazz musician who knows, ‘I have eight measures here and have to hit this note here and as long as I follow those rules everything else is up to me,’” Reitman says.
In creating the script for the Film Independent live-read this week, Reitman’s father got him the original script, as well as a transcription of the finished movie. He found himself adding many of the improvisations to the page, while still trying to preserve some of the original lines, which have never been heard before.
“Every important Venkman line is back in there, and there are about 30 of those,” Reitman says. “You can’t have Ghostbusters without ‘We came, we saw, we kicked its ass.’” '
