One of the biggest surprises on TV last year was the return of Luke Skywalker in the Season 2 finale of The Mandalorian, especially due to how technology managed to craft the appearance of a Luke who had only aged by a few years since the events of Star Wars: Return of the Jedi. Fans are still scratching their heads over how such a feat was pulled off, given that nearly 30 years have passed for Mark Hamill, with visual effects supervisor Hal Hickel recently addressing how important Hamill's involvement was in the cameo, while also withholding the specifics of how the scene was pulled off.
