With a show as secretive as “The Mandalorian,” it’s hard to get confirmations on things that are not clarified in the closing credits. Case in point, who exactly played Luke Skywalker in the season 2 finale? The credits list Max Lloyd Jones as “Double for Jedi,” and before that the credits mention one Mark Hamill as having something to do with the show. It is only now that showrunner Jon Favreau confirmed Hamill actually was on set to shoot his de-aged cameo.
