The critically acclaimed Star Wars series Andor, which chronicles the early days of the Rebel Alliance through the eyes of Cassian Andor, was originally envisioned as a Cold War-style spy drama akin to the classic Mission: Impossible television series. These early concepts were detailed in the official behind-the-scenes companion book, "The Art of Andor."

Jared Bush, known for his work on animated films like Encanto, was initially tasked with developing the series, then codenamed Whitesnake, in April 2018. Bush's outlines, titled Star Wars: Alliance and later Star Wars: Andor Five, focused heavily on Cassian Andor as an established intelligence operative within the Rebellion. The narrative would revolve around Cassian being falsely accused of being an Imperial mole after a significant rebel setback. To clear his name, he would undertake a mission to infiltrate the Imperial planet Okara and uncover the true traitor.

Dominic Sikking, Andor's lead graphic designer, noted in the companion book that the series was described to him as a spy drama featuring Cassian and a group of rebels infiltrating the Empire using "Cold War-style spycraft." Bush's concept placed a greater emphasis on espionage and Cassian undertaking specific missions, a focus that differs from the first season's approach, which prioritized establishing the Axis Network and Cassian's eventual recruitment into the Rebellion. While Cassian's role as an intelligence operative would have been more prominent from the outset in Bush's version, Season 2 of the actual show does delve more deeply into such mission-based storytelling.

Cassian's original companions in Bush's concept included Avnee, a planned love interest, and K-2SO. However, this iteration of the series never came to fruition. Tony Gilroy submitted his own pitch to Lucasfilm president Kathleen Kennedy, which ultimately led to Bush's vision being shelved.

Despite the success of Andor's first season, praised for its "intoxicating slow burn" and depiction of the sacrifices made by rebels, the original spy-centric concept remains a fascinating alternative. The possibility of Lucasfilm revisiting this initial idea, which would explore more complex spy work for Cassian from the series' inception, has been noted as something that would be met with interest.
