Who'll Star in Tim Burton's Addams Family Movie?

The combination of feverishly imaginative arrested child Tim Burton and the wry cartoons of Charles Addams are such a perfect fit it's a wonder it took so long for Burton to direct a 3-D stop-action animated movie of The Addams Family (not to be confused with the musical version currently on Broadway).

And now that word of the project has leaked out like pus from Uncle Fester, it's for us mortals to sit and wonder which big names will end up doing the voices of the creepily alluring lead roles.

This one is so easy I'm ashamed to even pose it as a question.

Obviously it'll be Johnny Depp and Helena Bonham Carter, duh.

But who'll play Thing?
