About Pound

Pound is a 1970 American comedy film written and directed by Robert Downey Sr. It was based on The Comeuppance, an Off-Off Broadway play written by Downey in 1961. It is about several dogs, along with a Siamese cat and a penguin, at a pound, as they await being euthanised; the animals are played by human actors. The film is best known for marking the acting debut of Downey's son and namesake, then-5-year-old Robert Jr., as Puppy.
