[The Sixth Wizard]

Err... What about Bilbo? And Gollum?

I think I subconsciously left them out because Bilbo looks so old in LOTR and Gollum's a CGI creation.

Anyway Bilbo should appear way younger. Sure, the ring kept him young, but he's only on the brink of adulthood in the Hobbit and twenty years younger than Frodo is in LOTR...
