Here's a link to a good, free, micribudget sf movie that I'd fairly good on it's own nerjs but had a special something that might make it particulary interesting to 40k players. It features a surprise appearance by an alien race that looks, and maybe even acts, a lot like a certain 40k race.
Seriously, these guys are so close to a certain 40k race I'm almost surprise gw didn't reflexively Sue them. I hope people like it.
