In George Miller’s 2015 Mad Max: Fury Road—a sequel to the post-apocalyptic chronicle Miller kicked off in the late 1970s, with Mel Gibson as a scrappy lone warrior seeking to preserve some vestige of civilization—Charlize Theron played Imperator Furiosa, a one-armed nut-buster fixed on a single goal: to free a bevy of sex slaves kept by a mouth-breathing warlord named Immortan Joe, who also happened to be her old boss.
