What are the differences between the DVD Versions and the original Theatrical Version?
A
The German VHS version is based on the Theatrical version and offers two more scenes than the DVD version. The latter, however, contains a scene which is missing in the Theatrical Version. The missing scenes are featured in the bonus material of the DVD version, though. A detailed comparison between both versions with pictures can be found here.
Q
What happened to the plot toward the end?
A
The story goes that the studio executives who originally greenlit the film left Paramount Studios midway through production. Joe Dante was called in to show a progress report of the unfinished film. Wanting to put up something against "Indiana Jones And The Temple of Doom" that summer, the executives ordered the film to be released in its present form. Dante was unable to do any reshoots or pick up shots. What we see is the unfinished version, giving us a glimpse at what the finished film was originally intended to be.
