And since the production designer on this film is the great Bo Welch, the sets were full-scale and fully-functional.(...) Welch is from the school of thought that if you can build something, you build it, and this film is a great example of that. They took over a big chunk of the Universal lot last summer and built as many full-sized sets as they could. My guess is that any one of those soundstages represented a larger investment than any complete season of the original Sid and Marty Krofft Land Of The Lost series, and theres something really crazy about that.
