That's pretty lore accurate, though, right?

Most Links are portrayed as being either kids/teenagers or very young-looking adults, and Zelda is often portrayed as being a more experienced character, still young but often already embroiled in the politics or conflicts that are core to the story's initial setup. Link usually shows character growth as he rises to the challenge, but Zelda is often a more static character, who starts the story fully fledged.

I've never heard of either actor, but a cursory Google to look at their various photos and I can see them working in the roles. Obviously assuming they can act, too.
