The show, created by Rebecca Sugar, follows the coming-of-age story of Steven Universe, who lives in the fictional town of Beach City with the Crystal Gems, magical humanoid aliens going by the names of Pearl, Garnet, and Amethyst. Being a half-Gem on his mother’s side and the only male on the team, Steven protects the world from their own kind as he learns about his growing powers.
Callison stopped by SYFY WIRE’s Live Stage during Emerald City Comic Con, where the young actor opened up to Katie Wilson about how he got his start as an actor, and nabbing the role of Steven.
“I was 14, and we got the email for the original pilot,” Callison told us. “For those of you that have seen it, it’s still floating around the internet in its early form. And it was like 10 lines of dialogue, the original extended theme song, and just some character breakdowns and descriptions. Pretty typical voiceover audition. But it definitely was on the quirky side, and it wanted me to really be unique and quirky and on the wild side of things and not do what I typically do for a typical cartoon audition, and that really resonated with me. Me and my coach spent about 90 minutes working on the initial audition and then a couple of rounds of callbacks, and then we did the pilot … and then I didn’t hear from them for like 10 months.”
Callison then went on to discuss what life has been like growing up with the character, which he calls “the single most helpful acting exercise I’ve ever done,” and how he personally related to Steven.
