Davis started in acting as the Ewok, Wicket, in Return of the Jedi, but has since diversified into roles where audiences actually get to see his face. Proving his commitment to the furry costume, he continued being the Ewok is both of the follow up films, Caravan of Courage: An Ewok Adventure and Ewoks: The Battle for Endor. Davis then returned to the Star Wars universe for The Phantom Menace, playing four brief uncredited roles. He was Wald, the Rodian playmate of Anakin Skywalker (for Rodian, think "looks like Greedo"), Weazel, one of the gamblers at the podrace (he's sat directly to the left of Watto), a street trader on Tatooine and he filled in as the body of Yoda for some of the walking scenes (Frank Oz still did the voice, naturally). On top of all that, he'll be in The Force Awakens, too! Although, fans don't know what his role will be yet. Hes now also famous for his roles as Professor Flitwick and Goblin Griphook in the Harry Potter film series, but to Doctor Who fans he'll be forever known as the disguised emperor, Porridge, in the 2013 episode Nightmare in Silver.
