During a recent Twitch live stream, Star Wars voice actor Sam Witwer revealed an interesting tidbit about Star Wars Rebels. Witwer, who voices Darth Maul on the hit series, was live-streaming his session playing the old The Force Unleashed video game alongside fellow voice actor David Collins, where he revealed that the iconic Starkiller character was originally slated to be part of the Star Wars Rebels TV series. Here's what Sam Witwer had to say, explaining that it was Rebels executive producer Dave Filoni who told him this Starkiller news.

"Dave did share with me, by the way, he considered making Starkiller an Inquisitor in Star Wars Rebels. It didn't quite fit the story that they were telling, but he did think about it because he thought that would be interesting."

Starkiller, born Galen Marek, was Darth Vader's secret apprentice in The Force Unleashed and its sequel. The player controls the character in both games. The first title consists of Starkiller hunting the remaining Jedi, with the story set between the events of Revenge of the Sith and A New Hope, honing his skills and training to eventually take on the Emperor himself so that he and Vader could rule the galaxy together. It's possible that this character could be featured in Season 4, with Season 4 confirmed to be the Star Wars Rebels final season.

The brand new trailer for season four of Star Wars Rebels debuted at Star Wars Celebration Orlando back in April. Promising an action-packed storyline that left fans eager for more, executive producer Dave Filoni was also on hand at the convention to deliver news of the show's must-see conclusion alongside the voice cast of the entire Ghost crew including Freddie Prinze Jr., Tiya Sircar, Taylor Gray, Vanessa Marshall and Steve Blum.

Now in production, the fourth and final season of Star Wars Rebels will premiere this fall on Disney XD and conclude the thrilling and inspiring galactic adventures of fan-favorites like Ezra Bridger, Sabine Wren and the entire Ghost crew! The critically acclaimed series has carried a new era of beloved characters, exploring storylines that span the entire Star Wars offering of movies, television, and diverse media. Season four promises a whole new batch of excitement and revelation as the series draws closer to the events of Star Wars Rebels.
