Ghosts of Geonosis

"Ghosts of Geonosis" is an upcoming two-part episode and winter premiere of Star Wars Rebels. It is the tenth and eleventh episode of the show's third season and the forty-ninth and fiftieth episode of the series overall. The episode features the Star Wars Rebels debut of Saw Gerrera, a character featured in the television series Star Wars: The Clone Wars and the feature film Rogue One: A Star Wars Story. The episode is set to air on January 7, 2017 on Disney XD.

Official description
The crew returns to Geonosis in search of a missing rebel team sent to investigate suspicious activity there, and are surprised by what they find.

Development
"Ghosts of Geonosis" is the first Star Wars Rebels episode to air after the release of Rogue One: A Star Wars Story, allowing it to tie directly into the feature film. In doing so, the production team chose to introduce Saw Gerrera to the show. The character was originally introduced in the fifth season of the television series Star Wars: The Clone Wars, and he was brought into live-action for Rogue One. The episode shows Gerrera and the crew of the Ghost investigating Geonosis. Although the characters will not yet know it, they will be on the trail of the Death Star that the Alliance to Restore the Republic ultimately learns about in Rogue One. Forest Whitaker, who portrayed Gerrera in the film, reprises his role for the episode, which helps bridge Gerrera's characterization in The Clone Wars and Rogue One.
