After a night of drinking Guiness at the local watering hole, an ordinary, working-class, family man in Dublin's life is turned upside-down when he wakes up as a rat.
Rat is a 2000 comedy film directed by Steve Barron and starring Imelda Staunton and Pete Postlethwaite. The film focuses on the transformation of a working-class man into a rat and how his family copes with the startling change. The film's scenario is partly based on Franz Kafka's The Metamorphosis.
