The wait is almost over for fans of Disney XD's Star Wars Rebels as the network announced today that season three of the hit program would premiere with a one-hour event on September 24th at 8:30 p.m. In the season opener titled "Steps into Shadow," a familiar face will also make his grand return to the Star Wars universe: Grand Admiral Thrawn.

Having established a secret base on Atollon, the Ghost crew, now led by a more powerful Ezra, strengthens the rebel fleet by acquiring new resources and recruits eager to stand against the Empire. However, the Imperial efforts to eliminate the rebellion are now being led by the coldly analytical Grand Admiral Thrawn, whose strategic, tactical and cultural insights make him a threat unlike any they have faced before. In season three, Ezra and Sabine take on new roles and challenges as the rebels prepare for their biggest mission yet – a direct assault on the Empire.

Star Wars Rebels is created by Dave Filoni, Simon Kinberg, and Carrie Beck. The Lucasfilm Animation production is executive produced by Filoni and Kinberg, and co-executive produced by Henry Gilroy.

The talented returning voice cast includes Freddie Prinze Jr. as Kanan, Vanessa Marshall as Hera, Steve Blum as Zeb, Tiya Sircar as Sabine, Taylor Gray as Ezra, Dee Bradley Baker as Captain Rex, Captain Gregor and Commander Wolffe, Sam Witwer as Darth Maul and David Oyelowo as Agent Kallus.  New to this season are Tom Baker (Doctor Who) as the intriguing Force-wise Bendu and Lars Mikkelsen (House of Cards) as the Star Wars Legends fan-favorite Grand Admiral Thrawn.

Before the season three premiere, catch Star Wars Rebels season two on Blu-ray and DVD starting August 30, 2016.
