Now here's my nomination for Most Ridiculous Montana Movie: Psycho Sheep of Butte. An extremely low-budget effort by a couple of Bozeman filmmakers, Psycho Sheep is a campy sci-fi horror parody ... with a storyline including space aliens and time travel, as well as carnivorous sheep and the Berkeley Pit. Maybe not the quintessential Butte film, but it definitely fits.
The movie is more than a little uneven, and you have to be in the right frame of mind to appreciate it, but it worked for me. I actually have a Psycho Sheep T-shirt, something that's guaranteed to draw attention wherever I go!
