Title: Darth Vader
Content:   Darth Vader was portrayed by bodybuilder David Prowse in the original film trilogy, with fencer Bob Anderson performing the character's lightsaber fight scenes.

Producer Rick McCallum said that Lloyd was "smart, mischievous and loves anything mechanical—just like Anakin."
