The Plague Dogs (1982) (UK-import)
Martin Rosen writes and directs this animated adventure based on the novel by Richard Adams. Two dogs, Snitter (voice of John Hurt) and Rowf (Christopher Benjamin), escape from a research institute and go on the run. Both animals have been purposely infected with a deadly virus, and as such, pose a dangerous threat to the human population. As the authorities give chase, the two dogs do their best to find their original owner and dream of a place where they will no longer be harmed by the cruelty of mankind.
