In the original Star Wars trilogy, Alec Guinness provided the voice for Darth Vader.

The statement is false because Alec Guinness did not provide the voice for Darth Vader in the original Star Wars trilogy. The voice of Darth Vader was performed by James Earl Jones, while Alec Guinness portrayed the character Obi-Wan Kenobi. Guinness played a pivotal role as Kenobi, serving as a mentor to Luke Skywalker and appearing in the original Star Wars film, "Star Wars: Episode IV - A New Hope" and its subsequent sequels, "The Empire Strikes Back" and "Return of the Jedi."
