Somebody should make a movie about some sort of vicious creature attacking people aboard a method of mass transportation. Until that happy day, we'll have the Blanks on a Blank
contest, sponsored by Austin's awesome Alamo Drafthouse. Competing teams of filmmakers drew randomly generated creatures and wheeled conveyances, then made their own terrifying high-concept thriller. Behold the terror of "Tarantulas on a Hovercraft" and "Sloths on a Tank!"
Many thanks to Freddy Tiffany for the tip.
