A short film made with the help of the Sundance film institute (and Terry Gilliam) by Quentin Tarantino as a demo version of the full length movie Reservoir Dogs - Wilde Hunde (1992). It helped to increase the budget for the full length movie. Tarantino plays Mr. White, Steve Buscemi plays Mr. Pink and Harvey Kietel plays Mr. Orange.
