If you want to find out if something is an illusion or not, ask the illusionists themselves, not members of the intended audience.
I'm amused that in Jeff Meldrum's new book he introduces the nearly 40 year old testimony of ONE individual within the professional costume community, Janos Prohaska, as evidence that Patty is not a guy-in-a-suit. Does Prohaska's opinion represent a consensus? By no means.
How about the testimony of Chris Walas?
"The separation between the leg and torso, however, is an obvious clue to me. When I saw it, I was shocked and angry. Shocked because I didn’t expect to see it and angry because I didn’t want to see it. I still want to believe that the subject in the Paterson footage is a real creature; and it is. It’s a human creature in a Sasquatch suit."

How about the testimony of Howard Berger, Bob Burns, and John Vulich?

How about the testimony of Rick Baker?
"Famed Hollywood creator of "Harry" (from the movie "Harry and the Hendersons"), Rick Baker, told Geraldo Rivera's "Now it can be told" (in 1992) show that "it looked like cheap, fake fur" after seeing the filmstrip."

And how about the testimony of perhaps the greatest costume FX guy out there today, Stan Winston? In what has got to be one of Bigfootery's biggest backfires, Winston is interviewed about the Patterson film as a "bonus" feature of the Sasquatch Odyssey DVD:
"Also appearing is one of Hollywood's greatest special effects legends, Stan Winston, creator of movie monsters such as the Jurassic Park dinosaurs, the apes in Congo, Alien, Predator, etc. Along with the late John Chambers (who created the apes in Planet of the Apes, and whom film director John Landis credits with being the man behind the Patterson-Gimlin footage creature from Bluff Creek on October 20, 1967), Winston is an undisputed master of movie trickery. He viewed the Patterson-Gimlin footage, and states: "It's a guy in a bad hair suit. Sorry." Later, "For under a thousand dollars -- in that day -- they could have had this suit made. If one of my [professional] colleagues created this for a movie, he'd be out of business."

Bigfootery has put itself in the position of ASKING THE WRONG GUYS. Asking Meldrum or Krantz or Bayanov about the film is kind of like asking the editor of Guns and Ammo whether Penn and Teller really catch bullets in their teeth or not. It's not a ballistic issue, it's an illusion issue.
