Question: what are uruk hai in lord of the rings?
Answer: In the movies Uruk-hai are described as a crossbreed between Orcs and "goblin-men". This is presumably a reference to the Goblin-men and Half-orcs in Saruman's service, creatures that blend the traits of Orcs and Men. These Uruks are sent after the Fellowship, and their leader is Lurtz, a movie-only character.
