We saw a minute-long teaser back in May, now Disney has unveiled an extended trailer for its upcoming animated series "Star Wars: Rebels". Set between "Star Wars: Episode III - Revenge of the Sith" and "Star Wars: Episode IV - A New Hope," the series showcases the ultimate formation of the Rebel Alliance against the now dominant power of the Galactic Empire. "Star Wars Rebels" will premiere in the fall as a one-hour special on Disney Channel, before debuting as a series on sister channel Disney XD worldwide.
