Wars: The Clone Wars and Star Wars Rebels supervising director Dave Filoni had stepped back from that position on the latter series so he could focus more on the series' writing as well as the development of future animated series for Lucasfilm. In July 2018, Filoni announced that a final season of The Clone Wars would be released on the streaming service Disney+ in 2020. The season includes a four episode arc introducing a squad of clone troopers with genetic mutations known as the Bad Batch; the episodes previously existed as story reels for an earlier, unfinished season of the series, and came directly from the plans of Star Wars creator George Lucas. Development Disney+ officially ordered a new series from Lucasfilm Animation in July 2020 titled Star Wars: The Bad Batch, a spin-off from the final season of The Clone Wars following the Bad Batch clones in the aftermath of the Clone War. The announcement described the series as Dave Filoni's vision, and he serves as executive producer alongside Lucasfilm's Athena Portillo, supervising director Brad Rau, and head writer Jennifer Corbett, with Lucasfilm's Carrie Beck and Josh Rimes as co-executive producer and producer, respectively. Filoni described the series as "very much in the vein" of The Clone Wars and said it would stay true to Lucas's vision for that series of telling epic, exciting adventure stories. In August 2021, before the release of the two-part first-season finale, the series was officially renewed for a second season. Casting The first trailer for the series, which released in December 2020, confirmed that Dee Bradley Baker would return from The Clone Wars as the voice of all the clone troopers in the series, including the members of the Bad Batch and Captain Rex. It also revealed that a younger version of the character Fennec Shand from The Mandalorian would be appearing in the series, and actress Ming-Na Wen soon confirmed that she would reprise her role as Shand. Additionally, Stephen Stanton and Andrew Kishino reprised their roles as Admiral Tarkin and Saw Gerrera, respectively. Music Kevin Kiner was confirmed to be scoring the series in January 2021, after previously scoring The Clone Wars and Rebels. He wrote the Bad Batch Theme for the final season of The Clone Wars, and described his score for The Bad Batch as an evolution from its predecessor with a mix of electronic and orchestral elements.
