I wouldn't mind seeing Batman as Spike, but I like Zeonic Freak's idea the best. Unfortunately, that won't happen, for many reasons, including the fact that, as far as I know, Steven Blum has never done a live-action role, and the fact that he is 43, while Spike is 27. At least Christian Bale does live-action roles, mostly live-action roles, and a lot of them, including many leaRAB, and he is 34, less than half as much older than Spike as Blum.
