Franchise's final installment offers the epic Battle of Hogwarts
Warwick Davis in 'Harry Potter and the Deathly Hallows Part II'
Warwick Davis plays Griphook, one of Gringotts Bank's Goblin employees in "Harry Potter and the Deathly Hallows Part II." He's also appeared in the series as Professor Flitwick.
Davis' sci-fi/fantasy resume goes back to "Return of the Jedi" (in which he played Wicket, the Ewok), and may still be best-known for playing the titular monster in the "Leprechaun" film series.
