I found these Behind The Scenes of Sylvanic videos about 5 days ago, I went to the Sylvanic website to watch them there but they weren't up at the time so I held off on posting them.
The BtS videos don't show any of the Bigfoot footage from Sylvanic, but are a decent watch any way. The videos mostly show Todd Standing going about his promo efforts and his work on conservation for Bigfoot, there are a couple points through out the videos that interested me, first was a brief follow up about Todd's appearance on the radio show Coast to Coast, he doesn't go into to much detail, but says he is in communication with Bugs and C2C, other than that not much else, secondly was getting the viewers reactions to the documentary as the left the theatre, most seemed pleasantly surprised by the Bigfoot footage. I can't remember in which videos these segments were as I watched them 5 days ago and wasn't taking notes.
It looks like a series of 8 videos, at the moment it goes from 1-4 skips 3 and goes straight to 8, so I'll post the first 4 here and update when the missing parts are available.
