Four-legged friends are easy to find.
But filmmaker Geoff Talbot is looking for a star with three legs.
Talbot is asking Twitter users to Tweet the following: "We’re searching Twitter 4 a 3 leg dog 2 star in motion picture. Tweet it on. Info@ http://geofftalbot.wordpress.com/help-find-scrap."
But not just any three-legged dog -- Scrap must specifically be missing a hind leg. The dog also must be medium sized with "big cinematic doggie eyes."
Overly aggressive dogs need not apply.
