Exhibit B-
This is a documentary showing how in no way could that Bigfoot be a guy in a suit.
First off, not even the best special effects wizards can recreate today, and this film was made in the 60s. Nowadays we have CGI so it'd be easier to edit in a fake bigfoot. In these days the ony solution was a suit. Robertson was dirt poor and so he couldn't afford to make a suit quite so realistic as in the tape.
