Justice grew up in Anaheim, California, which is home to the Disneyland theme park. As a teen, Justice already knew he wanted to be an actor, and hoped to work as a character actor at Disneyland over the summer. He even applied for a job there, but was rejected.
He told Jimmy Kimmel that instead of Disneyland, he worked at Knott's Berry Farm, which he jokingly called "Bootleg Disneyland." He wasn't interested in being one of the cowboy or pioneer characters at the park, and instead took visitors' tickets at the park entrance.
