Cancelled Series Star Wars: Underworld Was So Expensive, It Would've 'Blown Up' the Star Wars Universe

Author : Olivia Mar 19,2025

Rick McCallum, producer of the Star Wars prequels, recently revealed the staggering cost behind the cancelled Star Wars: Underworld series: a jaw-dropping $40 million per episode. This exorbitant budget, driven by the scale of each episode exceeding that of the films themselves, ultimately sealed its fate. McCallum explained on the Young Indy Chronicles podcast that even with the technology available at the time, reducing costs below $40 million proved impossible. He described the project's demise as "one of the great disappointments of our lives."

With 60 third-draft scripts already completed, showcasing a "sexy, violent, dark, challenging, complicated, and wonderful" Star Wars universe penned by top writers, the budget proved insurmountable. The estimated cost of $2.4 billion (60 scripts x $40 million/episode) was simply too much, even for George Lucas in the early 2000s. McCallum suggested that the series' ambitious scope would have fundamentally altered the Star Wars landscape, potentially preventing Disney's acquisition of the franchise. The project was ultimately shelved after Disney's purchase of Lucasfilm and Lucas's departure.

While McCallum remained tight-lipped on plot specifics, fan speculation consistently points to a storyline bridging the gap between Revenge of the Sith and A New Hope. Previous statements indicate the series would have introduced a fresh cast, significantly expanded the Star Wars universe, and targeted a mature audience, unlike the franchise's typical teen and child demographics.

Initially unveiled at Star Wars Celebration in 2005, and with test footage surfacing in 2020, Star Wars: Underworld remains a tantalizing "what if?" scenario. Sadly, it seems its ambitious vision will likely remain unrealized.
