First and foremost, I'm not sure if this will work with PC modems. Believe you need high-speed capability -- at least cable modem -- to watch this movie. It's a continuous broadband video feed that is 62 minutes long. The movie itself is a little over 15 minutes and the remainder is comprised of 'the filming of Monster of Plum Creek', 'the characters', 'scene compositon', and yes, even the 'outtakes.'
This is low-budget folks, complete with interspersed Rod Serling-like commentary.
The presentation is c/r 2003 by Douglas County (Colorado) Television.
While watching I was interrupted several times by phonecalls, but believe this presentation was based on a 1954 sighting. So, if you have nothing to do, here's the link. Scroll down to the Monster of Plum Creek and enjoy...(maybe that's not the right word). Oh, and I found this in Bobby Short's latest newsletter...

This thing is long. I am halfway through. The making of is saying it was a hoax perpetrated by a woman who lived there.

Right you are, Leeloo. Portrayed perhaps by the women clipping out the newspaper articles. What I found most interesting were the peoples comments in the follow on clips. A real study in human nature...

I'm glad I was able to remove my nose from the computer screen after the first 15 minutes I found the whole thing very good, well done.
