I posted last year about a couple of indie filmmakers who are tackling the idea of a Myst movie. Sadly, Patrick McIntire and Adrian Vanderbosch still haven't made a film -- last we heard, they had a script of roughly three zillion pages and were trying to slash it down to feature-length.
I still think that's pretty awesome, but even more awesome -- at a slightly different angle -- is this: their project has inspired a different couple of guys to become amateur filmmakers, from a standing start. Isaac Testerman and Nate Salciccioli have produced what they call an "Audition Project", offering to help out with the Mysteriacs film.
Regardless of where it goes, it is great: a ten-minute clip, covering several scenes of the basic Book of Ti'ana story. Shot on the classic shoestring budget, on locations (seriously: real caves), and it looks terrific. Plus director commentary at the end! The story stands on its own; my only note is that the character Aitrus you're watching is the grandfather of the Atrus in the Myst games.
