It doesn't help that both Ashmores, 41, have an affinity for appearing in comic-book, sci-fi, and otherwise "nerdy" projects.
Aaron played Jimmy Olsen, Clark Kent's best friend in four seasons of "Smallville," and has also appeared in "Fringe," "Killjoys," and most recently the Netflix series "Locke & Key," based on the comic of the same name.
His twin, Shawn, has even more comic-book cred to his name. He played Iceman in four "X-Men" movies and had a role in the second season of "The Boys" as Lamplighter. He's also appeared in "Smallville" and "Fringe," like his twin, and currently stars on "The Rookie."
