Stephen Ure is an Australian actor.
In Peter Jackson's The Lord of the Rings motion picture trilogy, he played Grishnákh in The Two Towers and Gorbag in The Return of the King. In The Hobbit: An Unexpected Journey and The Desolation of Smaug he portrayed the Hunter Orc Fimbul and the Goblin Grinnah through motion capture in the first film.
Interestingly, both characters that Ure played were trying to kill a hobbit before being struck by a weapon from the back (Grishnákh survived the piercing, Gorbag didn't).
He is known mostly for his work in The Lord of the Rings and The Hobbit, but is also known for Spartacus (the TV series) and Hounds.
