Michaela Zee editor Diego Luna never expected Cassian Andor to return to “Star Wars” following the Rebel spy’s heroic sacrifice in 2016’s “Rogue One: A Star Wars Story.” “I was shocked,” Luna told Variety at the “Andor” premiere in Los Angeles on Thursday. However, the titular star was ecstatic about the concept, saying that the show is “a beautiful journey, and an inspiring one.” “I think ‘Rogue One’ is a film about an event, but you don’t get to know much about these characters,” Luna said. “This long format [is] a great way to go deep into who they are and why they make the choices they make.”
