The Star Wars movies were released in the order of 4, 5, 6, 1, 2, 3 due to creative and narrative reasons. George Lucas originally created the original trilogy (Episodes IV-VI) first, starting with "A New Hope" in 1977, as he believed it was the most compelling part of the story. After the success of the original trilogy, he returned to create the prequel trilogy (Episodes I-III) in the late 1990s to early 2000s, which explored the backstory of key characters and events leading up to the original trilogy. This non-linear release helped build intrigue and expand the universe.

"Star Wars: The Clone Wars" was not officially cancelled; rather, it concluded after its sixth season due to a combination of factors. The show's narrative was wrapped up with the final season, and Disney's acquisition of Lucasfilm in 2012 led to a shift in focus towards new projects, including "Star Wars Rebels." The creators also wanted to explore different stories and formats within the Star Wars universe. While the series ended, it left a lasting impact and was later followed by additional content, including "The Bad Batch" and "Star Wars: The Clone Wars" unfinished arcs released on Disney+.

The fourth movie in the chronological order of the Star Wars saga is "Star Wars: Episode I - The Phantom Menace," released in 1999. However, if you're referring to the release order, it would be "Star Wars: Episode IV - A New Hope," which debuted in 1977. "Star Wars: The Clone Wars - Season 4" takes place between "Episode II - Attack of the Clones" and "Episode III - Revenge of the Sith," further exploring the events of the Clone Wars.

As of my last update in October 2023, there are no announcements regarding a new "Star Wars: The Clone Wars" movie. The series, which originally aired from 2008 to 2020, has been well-received, but its narrative primarily concluded with the final season released on Disney+. While there have been discussions about various "Star Wars" projects, including animated and live-action series, there hasn't been a specific confirmation about a dedicated Clone Wars film.
