During the early development of Clone Wars multimedia project, Dave Filoni pitched an early concept for the planned Star Wars: The Clone Wars new TV show. However, the original pitch was rejected by George Lucas.
George Lucas pitched the idea of an animated Clone Wars TV show in 2002, leading to the creation of Star Wars: Clone Wars, an animated series which aired from 2003 to 2005. During Celebration III, Lucas revealed his intentions to make another Clone Wars TV series along a live-action Star Wars TV show. Dave Filoni pitched an early concept featuring a group of characters traveling around the galaxy with a spaceship similar to the Millennium Falcon. The protagonists would have been an smuggler, his girlfriend, a Gungan named Lunker, a Jedi Padawan named Ashla and her Jedi Master.
However, when Lucas entered into the Clone Wars multimedia project, he decided to focus the show on the main characters of the Star Wars prequel trilogy films, like Anakin Skywalker and Obi-Wan Kenobi, scrapping Filoni's original pitch.
Despite the change, some of Filoni's ideas were later used in the Star Wars: The Clone Wars TV show, including the characters of Ashla (whose name was ultimately changed to Ahsoka Tano) and Lunker (who later appeared in the show's second season episode "Children of the Force").
