Variety writes that Charlize Theron and Tom Hardy have been confirmed for Mad Max 4 (also titled Fury Road). Writer/director George Miller helmed the first three installments between 1979 and 1985 and has already finished a script for the fourth, which will begin filming next August in Australia.
The first Mad Max helped launch the career of Mel Gibson, who went on to star in the two sequels (and of course a slew of other blockbusters). Its story involves a cop living in post-apocalyptic Australia who takes the law into his own hands after his family and friends are killed. The sequels, however, have little to do with the first movie, and the series' continuity is more or less non-existent.
