Last night’s episode of Star Wars: Skeleton Crew included several shocking twists, but one reveal in particular might hold the key to unlocking the series’ biggest mystery. The voice of the Supervisor — a shadowy figure who oversees all aspects of life on the planet At Attin — can be heard for the first time during an announcement to At Attin’s citizens, with the episode’s credits revealing that this cryptic character is played by none other than renowned actor, comedian, and writer, Stephen Fry.
