8. Xenophilius Lovegood
The Welsh actor Rhys Ifans peers out from under long white hair to play Xeno, editor of The Quibbler and father of the kidnapped Luna. Ifans is expert at mad eccentricity. His big scene, set in Xeno's off-kilter nest of a house, cuts even deeper when we realize Xeno must betray Harry, Hermoine and Ron.
