Count Dooku’s iconic curved lightsaber hilt is coincidentally similar to the curved hilt sabre of historic king and emperor Charlemagne, of whom Christopher Lee (who portrayed Count Dooku/Darth Tyranus) was a direct descendant.
Actor Christopher Lee served in the
British special forces during WWII.
While filming The Lord of the Rings:
The Return of the King, he was told
to scream when his character gets
stabbed. He replied, “Have you any
idea what kind of noise happens
when somebody’s stabbed in the
back? Because I do.” Source
