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

Music has always been a trademark of the Star Wars films and The Clone Wars. John Williams' masterful and suspenseful music is a pop culture touchstone, and The Clone Wars does well by honouring the maestro's gloomy tones.

Although Williams himself has not written any music specifically for the show, his most famous numbers still make it into the series. The most prominent examples can be found in Season Seven, as the threat of Order 66 begins to loom over the galaxy and the fate of our heroes. For example, as the Siege of Mandalore unfolds, we get the chance to hear the same music used in the opening of Revenge of the Sith, when Anakin and Obi-Wan are seen racing to save the Chancellor, showing that they are taking place at the same time.

But the most compelling use of Williams' work comes when Captain Rex gets the infamous order from Darth Sidious. It's a heartbreaking and unfortunately inevitable moment, as Rex turns on his friend and joins his brothers in trying to kill her. As Ahsoka holds them off, you can hear Williams' "Anakin's Dark Deeds" play, the same song used in Revenge when Darth Vader eliminates the Separatist Council.

It's a sneaky bit of TV, and easy to miss given the tension of the events unfolding, but once you notice it it's the kind of thing that makes you both smile and feel a sudden pang of nostalgia.
