I was thinking FMV game, but I'm guessing the answer is much sadder.

Ironically enough, it's from an Old Person. His page is full of green screen tests of multiple versions of himself in armor.

Yeah, I don't really know who this Douglas Herring dude is, but I stumbled across his channel while seeing what I can find with "green screen" as a keyword.

Mostly what I found was people imitating Superman flying, and it was pretty damn lame. This guy however, wow. As far as I'm concerned, these are what Orcs are going to look like in my head from now on.

He's also got a video that's from what I can tell, the only bits of film left from a full-length movie him and his buddies made back in 1982.

The Guardians of Terragarth looks like it would be a lot of fun to get drunk and MyST (or is it Riff now?) it. I sure hope there's an actual film out there, but my half-ass attempts at googling it has so far only turned up the trademark papers.

Wow. I sincerely hope the "Return from the Daemon's Lair" was not the most interesting part of the expedition.

Unpossible.
