Izzard will voice the diminutive Reepicheep in The Chronicles of Narnia: Prince Caspian, the sequel to CS Lewis classic The Lion, the Witch and the Wardrobe.
This is the first image of Reepicheep from the Disney movie, which is a mix of live action and computer-generated animation.
Izzard said of the role: “I didn’t see myself as Reepicheep but then I thought that it may be fun.
“And looking again at Reepicheep I realised that he has always been recorded in a high, slightly camp voice because of the overt language that he uses and his chivalrous nature, but actually he is a murderous little so-and-so of a mouse. I see him as the Mad Max of mice.”
Izzard, 46, fell in love with the Narnia books as a child.
“I read them all and I didn’t really read many things as a kid. The Narnia ones I really got into and I read every single one of them,” he said.
“I think it was the wish fulfillment – you go off and become adults, get swords and horses and fight battles.
