Frankly, I am astonished this hasn't been done before, or sold, as it would sell like hotcakes, but maybe the park/WDI/whoever doesn't have this material videotaped...though I expect they would.
Why hasn't there been a official DVD released featuring professional quality video of now defunct attractions/elements? Barring that, even the material they do have if not optimal. On the television shows and silver case DVD sets, there are hundreds, if not thousands, of tantalizing clips. For example, the same recycled Haunted Mansion clips filmed at some point before/after opening...did they just get those "money shots", so to speak, or did they film the entire ride? Imagine having a good quality video released with the old Mansion (beating heart bride, screaming pop ups, or even potentially, the holy grail of the Hatbox Ghost or the pre-HHG installation effect that's been rumored). Besides that...old Pirates of the Caribbean? America Sings? People Mover? Nature's Wonderland/Rainbow Caverns? Carousel of Progress? Old Tom Sawyer Island? 20,000 Leagues walkthrough exhibit? I am certain there exists more video footage than has been released of these attractions, somewhere...why not make use of it? And those are just scratching the surface...I am sure there is a ton of Disneyland related material out there on tape, in the hands of the company, that's never been released, or seen for years.
How about it, does any current/former CM of any level know of the existance of any of these items in a vault somewhere? Or truly did they just record these small bits and pieces of the park that keep showing up?
