After Revenge of the Sith released in 2005, there was a 7-year period where George Lucas and his company tried to develop a number of new video games, TV shows, and feature films that would take place in the vast Star Wars universe. Once Disney bought Lucasfilm in 2012, those developing projects were scrapped so Disney/Lucasfilm could instead focus on projects like Star Wars: The Force Awakens and the Star Wars Rebels animated series. There were a number of very promising projects just over the horizon from Lucasfilm, namely a live-action TV show called Star Wars: Underground and a video game called Star Wars 1313.
Star Wars: Underground took place in a dark and gritty world between Revenge of the Sith and A New Hope. It followed the seedy underbelly of organized crime on Coruscant and was described as a “Deadwood in space” and “Empire on steroids.” Star Wars 1313 was a video game from LucasArts that followed a bounty hunter making its way through the underground Level 1313 of Coruscant. Although both projects seemed to have a lot of potential, Disney ended development on both when they bought Lucasfilm in 2012. But now, there might be a chance we could see said TV show and video game come to fruition one day.
While talking to /Film, Lucasfilm president Kathleen Kennedy opened up about possibly taking another look at Star Wars: Underground and Star Wars 1313. When asked if Lucasfilm was finished with these projects, Kennedy responded:
No. No, interestingly enough, that's an area we’ve spent a lot of time, reading through the material that he developed is something we very much would like to explore. And there was 1313 the game... So our attitude is, we don’t want to throw any of that stuff away. It’s gold. And it’s something we’re spending a lot of time looking at, pouring through, discussing, and we may very well develop those things further. We definitely want to.
At one time, George Lucas wanted to make Star Wars: Underground himself, but thought the technology to make a high-level TV show set in space was too expensive. He wanted to wait until it was cost effective to make the TV show a reality. In the meantime, there are about 100 episodes already written and ready to go, while it's believed that it would last for about 400 episodes altogether when it was announced during Star Wars Celebration III in 2005.
As for Star Wars 1313, LucasArts announced the video game during E3 in Los Angeles a few months before Disney officially acquired the company. There was even concept art produced, which featured Boba Fett with a number of other bounty hunters and a large array of weapons like blasters and flamethrowers.
With the popularity of Star Wars today, it would be foolish for Lucasfilm not to at least explore the possibilities of Underworld and 1313. Star Wars Rebels is doing very well for Disney XD and something like a hard-edged Star Wars for mature audiences could be produced for a media platform like Netflix, which already houses Star Wars: Clone Wars. In fact, Marvel, another Disney company, has seen a lot of success expanding the MCU with more mature TV shows like Daredevil and Jessica Jones, so it would be plausible for Lucasfilm to do the same with Star Wars too.
Star Wars: Episode VII – The Force Awakens releases in theaters on December 18th, 2015, followed by Rogue One: A Star Wars Story on December 16th, 2016, Star Wars: Episode VIII on May 26th, 2017, and the Han Solo Star Wars Anthology film on May 25th, 2018. Star Wars: Episode IX is expected to reach theaters in 2019, followed by the third Star Wars Anthology film in 2020.
