Okay, follow along here....Beast Within is also known as "Virus Undead". It was shot in Germany with a full German crew and cast. However, it was shot in English because it was cheaper. Oh, and the director's name is Wolf Wolff. Other than that, there is just not a whole lot available on this movie aside from German Zombies.
When we reviewed Alexandre Aja's "Mirrors" this past summer on the podcast, we all agreed that it was an interesting concept that was pretty much ruined by the hilarity of Kiefer Sutherland's histrionic performance. And by "performance", I mean him shouting at things and shooting mirrors with guns. For those who didn't see it, no I'm not making that up.
