"Tony Gilroy, who had punched up the [Rogue One] movie’s script for reshoots. Gilroy—whose credits include writing the first four Bourne thrillers and writing and directing Michael Clayton—was developing a series that would explore Andor’s backstory, revealing what drew him into the galactic Rebellion and how he evolved from a self-serving nihilist into a selfless martyr. Luna’s call with Gilroy—the first time he heard the full plan for the Andor story—happened more than three years ago."
'On that day in mid-2019, when Luna was recruited for Andor, the actor remembers looking out the car window at the rooftops of the adjacent buildings, visualizing the tale about resistance-minded spies and near-death escapes. He was especially glad that Gilroy’s proposal included details that resonated personally. Luna describes Andor as a refugee story, with desperate people fleeing the Empire at the full force of its power. “It’s the journey of a migrant,” he says. “That feeling of having to move is behind this story, very profoundly and very strong. That shapes you as a person. It defines you in many ways, and what you are willing to do.”
Gilroy breathes deep and reveals a little more about Andor. “This guy gave his life for the galaxy, right? I mean, he consciously, soberly, without vanity or recognition, sacrificed himself. Who does that?” he asks. “That’s what this first season is about. It’s about him being really revolution-averse, and cynical, and lost, and kind of a mess.” The story begins with the destruction of Andor’s birth world, then follows him into adulthood, when he realizes he can’t run forever. “His adopted home will become the base of our whole first season, and we watch that place become radicalized,” Gilroy says. “Then we see another planet that’s completely taken apart in a colonial kind of way. The Empire is expanding rapidly. They’re wiping out anybody who’s in their way.” By journey’s end, Andor’s path will be to block theirs.
The show also focuses on the enigmatic Rebel leader Mon Mothma, played by Genevieve O’Reilly, who portrayed her as a young senator in Revenge of the Sith, then reprised the role in Rogue One. Mothma (then played by Caroline Blakiston) was the priestess-like figure in 1983’s Return of the Jedi who outlines weaknesses in the new Death Star, gravely intoning, “Many Bothans died to bring us this information.” In Andor, her story will run parallel to the title character, whom we know will eventually become one of her key agents. “It is a huge, orchestral, Dickensian ensemble cast,” says Gilroy."
