An original production used early draft script for possibly the greatest comedy of all time. According to Abrahams and the Zuckers they went through many versions of the script developing the film. This is an undated version from when it was still called Kentucky Fried Airplane! and the title has been written on the spine with the Kentucky Fried scrubbed out.
The general structure and scenes are the same with a different ordering. There are several scenes in here that never made the film including an interesting James Bond parody, and some scenes from the final picture are not in here such as the Saturday Night Fever dance. The white zone skit is actually an escalator in this version.
There is a cast list at the beginning which includes some interesting choices that I had never heard were considered before.
