Offspring is a 2009 horror film directed by Andrew van den Houten. The film centers on survivors of a feral flesh-eating tribe who abduct locals. It is based on the novel of the same name by Jack Ketchum, which is itself the sequel to Off Season. The cannibals in this film speak a language of grunts which is subtitled for the viewer. This did not happen in the sequel, as it only contains one of them.
