I Was a Rat is a UK children's drama series broadcast on BBC One in autumn 2001 based on the popular children's book I Was a Rat! or The Scarlet Slippers by Philip Pullman. It was aired in the Sunday tea-time slot which traditionally accommodates a children's drama series in the run-up to Christmas. The series was produced by Andy Rowley and starred Calum Worthy in the leading role, alongside Tom Conti and Brenda Fricker. It was adapted by Richard Carpenter, who won a BAFTA award for the work.
