British comedian Eddie Izzard will voice Narnia’s Reepicheep. (Interestingly enough, I was just discussing him elsewhere.) I don’t know if he’s exactly appropriate, but he’s a funny guy so I honestly don’t care.
For a quick immersion lesson, be sure to check out Thorn2200′s Lego animations of bits from Izzard’s routines. We’ve previously featured Death Star Canteen.
