Honestly, if you grew up watching Cartoon Network in the 2010s, you didn't just hear Zach Callison’s voice; you basically watched him grow up through your TV screen. Most people know him as the titular kid with the star on his shirt from Steven Universe, but the guy's resume is actually kind of wild when you look at the sheer variety of stuff he’s touched. From voicing a young Bruce Wayne to playing a recurring bully on The Goldbergs, Callison has been one of the busiest—and then, suddenly, one of the most elusive—actors in the industry.
He’s 28 now. Think about that for a second. When he started voicing Steven, he was barely a teenager. By the time Steven Universe Future wrapped up in 2020, he had spent nearly a decade inhabiting a character that went from a "goofball who loves fry bits" to a deeply traumatized young man dealing with the weight of the world. That transition wasn't just on-screen; Callison’s own voice famously dropped during production, forcing him to pitch his voice up to keep Steven sounding like Steven. It's that kind of dedication that makes his filmography worth a second look.
The Steven Universe Era and the "Vocal Shift"
You can't talk about zach callison movies and tv shows without starting with the big one. Steven Universe is the sun that the rest of his career orbits around. But here’s the thing most casual fans miss: he wasn't just Steven. He also voiced Onion (yes, the creepy silent kid), Pumpkin, and even some of the more abstract characters like Cactus Steven.
Working on a show like that for seven years is a marathon. In interviews and his own Reddit AMA, Callison mentioned how the audition process only took about ten minutes to find the tone, but years to master the emotional core. The "Change Your Mind" finale and the subsequent movie showed off a range most adult actors would kill for. He wasn't just "doing a voice"; he was singing complex Rebecca Sugar arrangements like "True Kinda Love" and "Change Your Mind" while portraying a nervous breakdown.

If you step away from the Gems, you'll find him all over the DC Animated Universe. It’s a bit of a trivia fact that he’s played Billy Batson (Shazam) more times than almost anyone else. He was in Superman/Shazam!: The Return of Black Adam, Justice League: War, and even the LEGO versions of the characters. Most recently, he’s been popping up in the Justice League: Crisis on Infinite Earths trilogy (2024), voicing both Dick Grayson and Damian Wayne. It's a weirdly perfect fit—he has this "youthful but burdened" quality to his voice that works for sidekicks and young heroes.
Then there’s the Disney stuff. Before he was a Crystal Gem, he was Prince James in Sofia the First. He also did the English dub for young Jiro Horikoshi in Studio Ghibli’s The Wind Rises. It's a massive range. One day he’s a Disney prince, the next he’s a street-smart kid named Skoochy in The Legend of Korra.
The Live-Action Transition
People often forget he has a face! He’s not just a voice in a booth. If you watch The Goldbergs, you'll recognize him as Brian Corbett. He’s appeared in:

- Fresh Off the Boat as Dan
- Henry Danger as Chet
- Just Add Magic as Chuck Hankins (a pretty significant recurring role)
- NCIS: Los Angeles (a darker, one-off dramatic turn)
His live-action work is usually more grounded. It’s the opposite of the "flailing arms" energy he says he uses for voice acting. He once told a crowd at a con that if you chopped his arms off, he wouldn't be able to voice act because he has to move so much to get the performance out. You don't see that in Grey's Anatomy: B-Team, where he played Oscar, but that manic energy is what made his early TV appearances like I'm in the Band stand out.
Why Did He Go Quiet?
Around 2020 and 2021, Callison notably stepped back. The internet started asking "where is Zach?" on Reddit every other week. Honestly, the answer is a mix of burnout and a pivot to music. His 2018 EP, A Picture Perfect Hollywood Heartbreak, was a massive departure. It’s a dark, theatrical concept album about the industry, mental health, and a fictionalized (or semi-autobiographical?) breakdown.
He’s been very open about the toll that growing up as a child actor takes on your psyche. He didn't disappear; he just stopped being "the kid." He took time to work on his own projects and deal with the "Hollywood heartbreak" he sang about. It’s a move a lot of child stars make, but he did it with a level of transparency that's pretty rare.

What to Watch (The Non-Steven List)
If you're looking to dive into his deeper cuts, start with Injustice (2021). His Damian Wayne is biting and arrogant—the polar opposite of Steven. Then, check out Skywatch, a sci-fi short where he plays Shaun. It shows his ability to carry a high-concept live-action narrative.
- Just Add Magic: He plays a character from the 1960s who was stuck in a "magic" state. It’s weird and he’s great in it.
- The Wind Rises: It’s Ghibli. It’s beautiful. His performance is subtle.
- Lego DC Shazam! Magic and Monsters: If you want the "classic" Zach energy, this is it.
Basically, Zach Callison isn't just a "voice actor." He’s a performer who happens to have spent his most formative years in a recording booth. Whether he's playing a Robin or a hipster in Astrid Clover, he brings this weirdly specific sincerity to everything.
If you want to support his current work, the best move is checking out his music and keeping an eye on the smaller indie shorts he’s been gravitating toward lately. He's moving away from the "brand" of being a cartoon star and into being a multifaceted creator. It’s a transition that’s hard to pull off, but he’s doing it on his own terms.
