10 Mind-Blowing Facts You Didn't Know About Star Wars: The Clone Wars

Since we're on the subject of Captain Rex and the clones who give the series its name, we're taking a look here at the veteran clone's conception and the work that goes into personalising men who sound and look the same.

Rex was originally going to be called Alpha, after a clone called Alpha-17 who appeared in the comic Star Wars: Republic, but the name was scrapped because Lucas felt the main cast featured too much alliteration and not enough diversity - Anakin, Ahsoka and R2-D2 (Artoo). Lucas then decided to call him Rex instead, and gave him the job of being the central clone character of the show.

Enter Dee Bradley Baker, who had the deceptively easy job of voicing the clones. Despite all the troopers effectively being the same person, Baker knew as well as Lucas and showrunner Dave Filoni that the essence of the show was to humanise the clones. Baker thus went to great lengths to differentiate the troopers, recording all their lines separately and adding inflections on key adjectives for each one.

Rex was given the most thought due to his large role on the show, and Baker and Filoni even made a "clone triangle" to help rank the troopers by the importance of their role on the show, which Rex topped.

It's a nice look into what went into making the show, and how much effort was put into the little things by the voice artists involved.
