It is weird. Genuinely weird to see a TIE Fighter with X-wing foils or a white-clad, redeemed Darth Vader—now "Jedi Vader"—cracking jokes about the Force. But that’s the charm of the Disney+ special that flipped the galaxy on its head. When the "Cornerstone" of the Star Wars universe gets yanked out, everything breaks, and the cast of LEGO Star Wars Rebuild the Galaxy had the monumental task of making this "Sig-and-Dev" adventure feel like a real Star Wars story despite the literal pieces being swapped around.
You’ve got a mix of legendary film actors returning to their roles and some of the most prolific voice talent in the industry. It’s not just a paycheck gig. You can hear the fun they’re having. Gaten Matarazzo, who most of us know as Dustin from Stranger Things, carries the emotional weight as Sig Greebling. He’s the heart of the show. He plays Sig with this sort of frantic, "I’m the only one who remembers how things are supposed to be" energy that keeps the stakes feeling real even when there’s a "Beach Bomb" Palpatine running around.
The Return of the Legends
Honestly, the biggest shock for a lot of fans was seeing Mark Hamill’s name. We’ve seen him do voice work for decades—obviously, his Joker is iconic—but hearing him play a "bum" version of Luke Skywalker is a trip. This isn't the stoic Master from the sequels or the farm boy from '77. This is a Luke who never left Tatooine, or rather, a Luke who is caught in the gears of a broken reality. Hamill brings a raspy, slightly unhinged quality to the character that highlights just how much the "Rebuild the Galaxy" hook actually matters.
Then there’s Ahmed Best.
People who grew up with the prequels know the history there. Seeing him return not as the clumsy Jar Jar Binks we knew, but as Darth Jar Jar, felt like a fever dream come to life. It’s a fan theory that existed on Reddit and message boards for literally twenty years. Having the original actor come back to voice a Sith Lord version of his character is the kind of meta-commentary that only LEGO Star Wars can pull off. Best uses a lower, more menacing register that still keeps those distinctive Gungan inflections. It’s brilliant.

While the big movie stars get the headlines, the heavy lifting often comes from the "pros." Tony Revolori plays Dev Greebling, Sig’s brother. Revolori, who you’ll recognize as Flash Thompson from the recent Spider-Man films, provides the perfect foil to Matarazzo. Their chemistry—even in a recording booth—is what makes the brotherly rift work. When Dev turns to the dark side (or the "Lego-fied" version of it), Revolori shifts his tone just enough to be threatening without losing the brotherly connection.
Bobby Moynihan is in this too. He plays Jedi Bob.
If you aren't a deep-cut LEGO nerd, you might not know who Jedi Bob is. He was an anonymous minifig from a 2003 Republic Gunship set. Fans named him "Bob," and now he’s a central character voiced by a Saturday Night Live alum. Moynihan brings a certain "tired mentor" vibe to Bob. It’s hilarious. He’s basically playing the Obi-Wan role but with the self-awareness of someone who knows he’s a plastic toy.
The Support Squad
- Marsai Martin: She voices Yesi Scala. She’s the spark plug of the group, bringing a lot of the grounded, "street-level" perspective to the chaos.
- Michael Cusack: He plays Servo. Every Star Wars story needs a droid, and Cusack (the creator of Smiling Friends) gives Servo a personality that is distinct from the C-3POs and R2-Ds of the world.
- Shelby Young: A veteran of the franchise who has voiced Leia and various characters in The Bad Batch. She’s incredibly versatile.
Why the Voice Cast Matters for SEO and Fans Alike
When you search for the cast of LEGO Star Wars Rebuild the Galaxy, you’re usually looking for that one voice that sounded familiar but you couldn't quite place. Most people don't realize that Star Wars animation has a "revolving door" of elite talent.

Take Dee Bradley Baker. The man is a legend. He voiced every single clone in The Clone Wars. In this special, he’s back, but because the galaxy is "rebuilt," the roles are skewed. It’s a masterclass in vocal range. He can make two characters sound completely different even if they share the same genetic code.
It is also worth noting the inclusion of Matthew Wood. Wood is a sound designer at Skywalker Sound but has been the voice of General Grievous and the Battle Droids for years. Hearing those "Roger Roger" lines in a new context provides a sense of continuity. Even when the world is upside down, the sounds are right.
The Complexity of the Recording Process
Voice acting for LEGO isn't just about reading lines. It’s about timing. The animation style is "staccato." It mimics the way a child would move toys. Because of this, the actors often have to "over-act" with their voices to compensate for the limited facial expressions of a plastic minifig.
Matarazzo mentioned in interviews that recording for Sig was a physical process. You can’t just stand still. You have to grunt, heave, and move to make the action sequences sound authentic. The result is a performance that feels much more high-stakes than you’d expect from a show where characters have yellow "claw" hands.

Addressing the "Alt-History" Concept
The brilliance of this cast is how they handle the "What If?" nature of the script. Naomi Ackie (who was Jannah in The Rise of Skywalker) and Kelly Marie Tran (Rose Tico) have been involved in the LEGO universe before, and their presence helps bridge the gap between the "official" canon and this wild LEGO sandbox.
It’s a tough balance. You want to honor the characters, but you also have to lean into the joke. When the cast performs these "remixed" versions of themselves, they have to play it straight. The humor comes from the situation, not from the actors "winking" at the camera too hard. Mark Hamill is the king of this. He plays Luke with total sincerity, which makes the fact that he’s a disheveled desert hermit in a LEGO world even funnier.
How to Experience the Cast's Work Best
If you’re diving into this, don't just watch it on your phone speakers. The sound mix is actually quite dense. They used a lot of original Ben Burtt sound effects from the 1977 archives. Hearing the actual TIE Fighter scream or the hum of a lightsaber alongside these performances creates a weirdly immersive experience.
Actionable Takeaways for Star Wars Fans:
- Watch for the cameos: Beyond the main cast, keep your ears open for "legacy" voices. Many actors from The Clone Wars and Rebels pop up in minor roles.
- Check out the "making of" clips: Disney often releases snippets of Gaten Matarazzo and Bobby Moynihan in the booth. It changes how you see the animation.
- Compare to the "Original" Canon: If you’re a lore nerd, listen to how Mark Hamill’s Luke here differs from his voice in Forces of Destiny. The subtle shifts in his performance tell you a lot about this "rebuilt" Luke’s mental state.
- Explore the LEGO sets: A lot of these characters, like Jedi Bob and Darth Jar Jar, were released as actual physical minifigs. Seeing the toy while hearing the voice adds another layer to the meta-narrative.
The cast of LEGO Star Wars Rebuild the Galaxy succeeded because they didn't treat it as "just a cartoon." They treated it like a Star Wars story that just happened to be made of bricks. Whether it's the nostalgia of Hamill and Best or the fresh energy of Matarazzo and Revolori, the vocal performances are the glue holding this chaotic, inverted galaxy together.
To get the most out of your Star Wars binge, go back and watch the original LEGO Star Wars Holiday Special or Terrifying Tales. You’ll notice a lot of the same voice actors (like James Arnold Taylor or Matt Lanter) popping up, creating a "LEGO Star Wars Cinematic Universe" that’s honestly more consistent than some of the live-action films. Pay attention to the credits—you’ll be surprised at how many "big" names do uncredited bit parts just because they love the franchise.
