The first trailer for LucasFilm's highly-anticipated animated series Star Wars Rebels is set to debut Monday, October 7 at 8:30 PM ET on Disney XD, during the series premiere of Mighty Med.

No cast members have been officially announced yet, although we reported last month that David Oyelowo, Freddie Prinze Jr., Vanessa Marshall, Taylor Gray and Steve Blum are in talks for unspecified roles.

The series is set between the events of Star Wars: Episode III - Revenge of the Sith and Star Wars: Episode IV - A New Hope, which follows the formation of the nascent Rebel Alliance as the Empire continues to wipe out any remaining Jedi Knights in existence.

The series was created by Simon Kinberg (Elysium), who is executive producing alongside Star Wars: The Clone Wars producers Dave Filoni and Greg Weisman. We reported in June that several cast and crew members from Star Wars: The Clone Wars will return for this series, set to debut with a one hour special on The Disney Channel before premiering as a weekly half-hour series on Disney XD.
