Although alanborky at Cryptomundo said something that really made me think:
[Movie description:]one of the hiker guys grabs one of his lady friends by the hand and pulls her toward Bigfoot. He coaxes her into making contact with the beast. Demurely, she approaches and holds out her delicate hand. Bigfoot sniffs her politely, then…
... this might be me being a bit too clever, but the above snippet of scene description immediately brought to my mind that part of the Ancient Sumerian Gilgamesh epic where Gilgamesh arranges for his potential adversary the wild man Enkidu to lose his innocence by being seduced by a temple courtesan.
You could argue, then, that ‘porno’ and ‘Bigfoot’ have been connected right from the dawn of civilisation.
Frankly, I don't see how you could argue against it.
