Acclaimed actor and EGOT winner James Earl Jones is retiring from one of his most famous roles. Jones has voiced Darth Vader, the iconic villain of the Star Wars franchise, since 1977’s Star Wars: Episode IV – A New Hope. His booming, menacing voice was an integral part of creating one of cinema’s greatest villains, but at 91 years old, Jones is stepping away from the role. The actor has signed over archival voice recordings to Lucasfilm, which has recruited Ukrainian start-up Respeecher to replicate Jones’s voice using A.I. technology. A new article from Vanity Fair delves into the company, and how its employees have managed to continue working during the Russian invasion of the Ukraine.

Respeecher has replicated the voice of young Luke Skywalker (Mark Hamill) for The Book of Boba Fett, and replicated Jones’s voice as Vader for Obi-Wan Kenobi. Jones last voiced Vader with just one line of dialogue in 2019’s The Rise of Skywalker. Lucasfilm supervising sound editor Matthew Wood said of Jones, “He had mentioned he was looking into winding down this particular character, … So how do we move forward?” Wood introduced Jones to Respeecher’s technology, who signed off on his archival voice recordings and lent his expertise to guide the character. Wood called Jones “a benevolent godfather,” for consulting on the process. Jones and his family praised the final result in Obi-Wan Kenobi, crediting Respeecher’s tireless work.
