Who He? Whadya, live on Mars? He's Harry Potter, the Boy Who Lived. Scar on his forehead, wears glasses, a bit short?

Why He? Well, Potter will finish shooting this spring for the last time, so Radcliffe's set to retire from his steady job - and he's still young. While he'd be a slightly short Spidey, and his facility for accents remains largely untested (aside from a decent Aussie turn in December Boys), at least the pressures of a major franchise would be business as usual for him.
