A few more images. Look at that cover art. It feels like they spent more on that than the films' budgets.
I saw Red Letter Media on YouTube review a couple of these. They look bad but yeah I think the second one kind of looked like a guilty pleasure.
You mention John Allen Nelson. I mostly know him from a short lived live-action syndicated show based on Sheena, Queen of the Jungle. He was the wisecracking jungle guide guy, romantic interest. Sheena was played by Gena Lee Nolin and they had both been on Baywatch together a few years before. For some reason in this version Sheena was like Manimal and could morph into animals with terrible special effects.
You're right the poster art, while great, is false advertising. I doubt Nelson could match the poster guy's physique.
