 Eddie Izzard as the voice of Reepicheep , a swashbuckling mouse . Over 100 actors auditioned to voice the character . Izzard approached Reepicheep as less camp and more of a bloodthirsty assassin with a sense of honour ( a cross between Mad Max and a Stormtrooper from Star Wars ) : Izzard interpreted Reepicheep as someone whose family was killed by the Telmarines . The Narnia series were some of the few books Izzard read as a child , and he cherished them . When discussing Reepicheep to the animators , Adamson told them to rent as many Errol Flynn films as possible . Adamson credits Izzard for making the role his own ; beforehand , the director was approaching the character similarly to Puss in Boots in Shrek 2 .
