Charlize Theron And Tom Hardy Join 'Mad Max: Fury Road' Cast

DESCWell, that was fast. Barely a week since they were first rumored to be a part of the new "Mad Max" sequel, the news is official — Charlize Theron and Tom Hardy are joining the cast of the George Miller-directed film.

According to separate reports in Variety and The Hollywood Reporter, both actors have signed onto "Mad Max: Fury Road," the fourth installment in the action-packed franchise.

Hardy, best known for his role as Handsome Bob in "RocknRolla," is set to replace Mel Gibson as the titular Max, while Theron joins the cast in an unspecified role as the female lead.

The "Mad Max" franchise takes place in a post-apocalyptic Australia populated by wastelands, vicious inhabitants and general lawlessness. Following the deaths of his wife and son, police officer Max Rockatansky ventures off into the great unknown of Australia's wastelands, with his own humanity hanging on by a very thin thread.

The plot line for "Fury Road" is currently under wraps, though Miller recently talked about the various technicalities involved in the film — specifically, the highly functional and super fast vehicles that will be used in the movie. The development of these cars is what's delayed the movie thus far, according to the director, but it's a necessary evil considering his desire to rely heavily on stunt work as opposed to CGI. That sounds fine by me.

For fans still holding out hope that Gibson might make a return to the franchise a la Leonard Nimoy's "Star Trek" role as an older, alternate universe Spock, don't hold your breath — sure, some sort of future glimpse could always happen, but THR reinforces long-standing reports that Gibson won't be involved in the fourth film.
