It seems like everybody wants to be involved in Star Wars. While the previous animated shows from LucasFilm had boasted an incredible array of voice talent, Star Wars: Rebels perhaps features a wider array the most of those other series. Even in the main cast, the likes of Lars Mikkelsen, Freddie Prinze Jr., and Ashley Eckstein lend their unique voices to major roles.
Across the show, there have been a number of other notable actors who have had a fun cameo or even a much larger role, and fans may be surprised to learn that they featured in the galaxy far far away. Most of these performers are likely lifelong fans of the franchise and have contributed a colorful array of characters to the brand.
Seth Green
Seth Green, a comedian, writer, and actor, is no stranger to the Star Wars universe. He's previously appeared in The Clone Wars and The Bad Batch as both the droid Todo 360 in multiple episodes and Ion Papanoida. The actor is clearly a huge fan of the brand and lent his voice to yet another character in Rebels.
The Robot Chicken star came aboard as Captain Seevor, in a limited appearance. The Trandoshan was part of a family dedicated to mining on Lothal and was largely serving an antagonistic role. Looking to contact the Empire at Ezra and the Rebels' appearance, he would die ironically in an accident, slipping on a lightsaber.
Dave Filoni
Chopper might just be one of the most underrated characters in the Star Wars universe, but fans might not know that it's Dave Filoni that actually provides many of the sounds for this charismatic and grumpy droid. Filoni is the mastermind behind the animated shows at LucasFilm and is heavily involved in the live-action projects on Disney+.
Because of his connection to the production process, Dave Filoni has appeared as countless characters. In the context of Rebels besides Chopper, Filoni has voiced a number of minor characters including Stormtroopers like Tk-626. Outside of this, he's even been a Rebel Pilot in live-action!
It's well documented that Josh Gad loves Star Wars. He even spent plenty of time trying to get the secrets of the sequel trilogy out of his friend, Rey actress Daisy Ridley. The actor has also been a part of major Disney movies like Frozen and Beauty And The Beast.
For Star Wars: Rebels Gad was brought in to lend his talents to a minor role. With cybernetic enhancements, Gad voiced LT-319, a controller working for the Empire who came in contact with the Rebels at the center of the series. While his plot sought to see Chopper reprogrammed he would ultimately perish during his efforts.
David Oyelowo
David Oyelowo is an incredibly talented actor, portraying parts in the likes of Selma, A United Kingdom, The Girl Before, and Chaos Walking. Despite the range of parts he has played and the prestige brought with his name, audiences don't necessarily know that he has had a major role throughout Star Wars: Rebels.
Oyelowo portrayed one of the best characters of the series in Agent Kallus, an Imperial operative who became disillusioned with what the Empire actually represented and began working as a spy for the Rebels. The performance is perhaps the best of the show as the depth of the character is slowly unraveled.
Warwick Davis
Warwick Davis will certainly not be an unfamiliar name for Star Wars fans. While the actor has played major roles in huge franchises like Harry Potter and Willow, he has spent most of his career as part of the Star Wars universe and may be best known for portraying the Ewok Wicket.
In Star Wars: Rebels he was Grand Admiral Thrawn's personal defender, Rukh, who served the Empire as a bodyguard and assassin. As a highly skilled warrior, this Noghri put his life on the line and thus paid the price of serving on the wrong side of the war, perishing during the rise of Lothal.
Genevieve O'Reilly
Iconic roles from The Matrix, Tolkien, and The Walking Dead are just some of the credits to Genevieve O'Reilly's name. She brings rich performances to every role she's given, but for Star Wars O'Reilly had the unenviable task of trying to bring a legacy character to life in a way that respected the original portrayal.
The performer has appeared in multiple Star Wars projects as the Republic leader Mon Mothma. As one of the key personalities within the Rebellion, Mon Mothma plays a part in Rebels and is once again voiced by Genevieve O'Reilly who clearly feels passionate about taking ownership of this beloved character.
Tom Baker
Tom Baker is best known to the world as the Fourth Doctor in the long-running sci-fi show Doctor Who. The actor has a presence unlike anyone else and carries with him a voice that features a range of emotions, conveying both wisdom and great charm.
There are plenty of twists and turns throughout Rebels but as the show dives into Jedi lore, the narratives being produced become far more mystical in nature. Tom Baker was brought in to voice the role of Bendu, a Force-sensitive being of immense power who guided the Jedi in training.
Sarah Michelle Gellar
Sarah Michelle Gellar, the wife of Freddie Prinze Jr. who voices Kanan in the show, has a great filmography to her name. From the Scooby-Doo series to Buffy The Vampire Slayer and Masters of the Universe: Revelation, Gellar is used to being a part of global stories.
For Star Wars: Rebels she took a much darker turn, voicing the Inquisitor known as Seventh Sister, who worked on behalf of the Sith and Empire in her hunt for any remaining Jedi. Her performance was chilling and the character would eventually meet her match in Darth Maul.
Clancy Brown
Clancy Brown has had a storied career. Some of the releases he has been involved with include John Wick, Shawshank Redemption, SpongeBob Squarepants, and Invincible. Indeed, while his live-action work is impressive, he has lent his voice to countless iconic parts.
For Star Wars, Brown might have had a brief appearance in The Mandalorian and voiced Savage Opress, but in an interesting connection he also briefly cameoed in live-action as Ryder Azadi who he voices in Rebels. The Lothal Rebel leader would help to liberate the planet after defecting from the Empire.
Tobias Menzies
Tobias Menzies, who has appeared in Game Of Thrones, Casino Royale and The Crown, often plays class and sophistication very well, sometimes with a much darker undertone. Those skills came into play when he was brought into the Star Wars family.
In Star Wars: Rebels Menzies surprisingly voices Tiber Saxon, another Empire ally dedicated to upholding their regime in the galaxy. As the representative of Mandalore and the brother of Gar Saxon, Tiber has deep familial ties that helped to guide his politics and position on his homeworld. Once again, he would die in service of the Emperor.
