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.

Lucas chose to have a different actor be the voice of Vader, since Prowse had a strong West Country English accent that led the rest of the cast to nickname him "Darth Farmer". Lucas originally intended for Orson Welles to voice Vader, but after deciding that Welles's voice would be too recognizable, he cast the lesser-known James Earl Jones instead. Jones initially felt
