Uglúk was the Uruk-hai who captained the Uruk-hai scouts who stole Merry and Pippen. In the flim Lurtz was the frist
to command the squard and Uglúk took over, but in the book Lurtz never led the scouts-Uglúk was the leader all the time. He was a large and strong Uruk-hai, but was killed by riders of Rohan, possibly Éomer. He was played by Nathaniel Lees in Peter Jackson's movie adaptation of The Two Towers.
