One day ahead of a highly-anticipated television premiere, Disney Channels Worldwide President and Chief Creative Officer Gary Marsh announced plans to produce a second season of the animated series Star Wars Rebels from Lucasfilm.

Marsh said, “The global expectations for this series could not have been any higher. And I am proud to say that the team at Lucasfilm has delivered something that has surpassed even that incredibly high bar – artistically and thematically.”

Star Wars Rebels has received acclaim from critics and fans alike since its advance debut screening at San Diego Comic-Con in July, followed by special previews this week on WATCH Disney XD and other digital platforms. Star Wars Rebels will be introduced via a television movie, Star Wars Rebels: Spark of Rebellion, premiering Friday, October 3 (9:00 p.m., ET/PT) on Disney Channel in the U.S. and Monday, October 6 (8:00 p.m., ET/PT) on Disney XD in the U.S.  It ushers in the series beginning Monday, October 13 (9:00 p.m., ET/PT) on Disney XD in the U.S.  The series will air in 34 languages across 163 countries in over 400 million households.

“We all love making ‘Rebels,’ so we couldn’t be happier that it’s moving into a second season,” says Lucasfilm VP of Creative Development, Kiri Hart.  “Our fantastic creative team is dreaming up new stories for the crew of the Ghost that will expand their experience of the galaxy and deepen their heroes’ journeys. The fan response to the show has been amazing, humbling and inspiring. We’re looking forward to the adventure ahead.”

The creative team behind the second season of Star Wars Rebels includes Executive Producers Simon Kinberg and Dave Filoni, and Co-Executive Producer and Supervising Writer Henry Gilroy.

Star Wars Rebels continues the epic story-telling tradition that has captivated generations of Star Wars fans since 1977.  Its story is set in the era between the film’s prequel trilogy and original trilogy and is in a unique position to bridge the two both aesthetically and generationally.  Honoring the past while moving boldly into the future, it features fantastic icons from Star Wars while introducing a new generation to the far corners of the galaxy, one full of exotic new creatures and characters. “

The one interesting note from this announcement is that Executive Producer Greg Weisman was not listed as one of the producers for season 2, but that writer Henry Gilroy will now be the Co-Executive Producer for the second season. So it looks Greg Weisman’s work on the series will only be for season 1. But it’s definitely great to see that Disney is showing this much confidence in the show to already order a second season before the premiere actually airs. But really, there wasn’t any doubt that Dave Filoni and his crew would deliver another great “Star Wars” series!

You’ll be able to see for yourself how good the show is tomorrow, when it debuts on The Disney Channel at 9:00 PM!
