Ghost in the Shell was groundbreaking, visually and thematically. The 1995 Japanese animated film (or anime) was unapologetically for adults. The story focuses on a cyborg cop whose body is synthetic but her brain is organic. As she chases down a mysterious hacker, Major Motoko Kusanagi grapples with what it means to be alive. When Scarlett Johansson was cast as The Major in the live-action remake, there was an outcry over whitewashing. But the reaction in Japan has been different. Roland Kelts (author of "Japanamerica"), journalist Emily Yoshida and Tufts University professor Susan Napier discuss the racial politics of anime.
