I stumbled across this gem uploaded by “A&A Home Movies” on YouTube. It’s an incredibly in depth look (over an hour long) at classic Movie World from 1992, containing full recordings of numerous defunct attractions and shows in decent quality. (For some reason, YouTube won’t let me embed it, so here’s a link):

Also found this video from “Roger Garrod” showing the park under construction in early 1991! 

 

Nice finds, but I can not understand why some people are dead-set determined to pipe unrelated music over the top of videos like the Garrod one.  It adds absolutely nothing, and in-fact detracts from the historical value.
