Richard LeParmentier, the actor most famous for playing Admiral Motti in Star Wars Episode IV: A New Hope, has died at the age of 66.

The actor, who lived in the U.K., was reportedly visiting relatives in Austin, Texas at the time of his death. The cause of his death has not been released.

LeParmentier had a long career on screen, appearing in over thirty movies and TV shows. His acting credits include roles in Rollerball, Superman II, Octopussy, and Who Framed Roger Rabbit.

LeParmentier’s most well-known role, however, was as Admiral Motti in the first Star Wars movie. In his memorable appearance, Admiral Motti expresses overconfidence in the Death Star, saying, “This station is now the ultimate power in the universe.” He goes on to dismiss Darth Vader‘s musings on the power of the force, and receives the first on-screen instance of a ‘force choke’ in history.
