Ilan Mitchell-Smith (born June 29, 1969) is an American academic and former actor, best known as a co-star of the film Weird Science (1985) and Andy McCalister in Superboy.

While there on his scholarship, he was discovered by a casting director and his film career began in 1982 at age 12 when he played a younger version of the title character in Sidney Lumet's Daniel.

The film focuses on two nerdy teenage boys who create a woman of their own (played by Kelly LeBrock), as they are unable to find girlfriends.

Recently, Mitchell-Smith has performed select voiceover work (recording for two episodes—"Moon Warriors" and "Heads Will Roll"—of Fox's Axe Cop).

Mitchell-Smith has published on Dungeons & Dragons,[6] and is a staff writer for Talk Wargaming and writes a column for Forces of Geek called "Playing the Nerd".
