#19: Rhys Ifans as Sirius Black
Sirius Black initially was in negotiation with Rhys Ifans. Later, the role went to Gary Oldman, playing an unforgettable concoction of danger with warmth in the character. Interestingly, Ifans later entered the Harry Potter universe as Xenophilius Lovegood, Luna’s eccentric father in Deathly Hallows, giving him his shot at Hogwarts after all.
