Mad Max: Fury Road, the sequel to 30 years prior Mad Max: Beyond Thunderdome, has gone on to become this year's biggest action movie so far. Released in May, the film has Tom Hardy as the iconic Mad Max, and Charlize Theron as Imperator Furiosa.

Making $350 million worldwide, the George Miller project is now creating Oscar buzz as well as rumours of a sequel. Deadline spoke to Miller this week about the reaction to Fury Road and what it means for the franchise:

On the critical acclaim of Fury Road:

"One thing about this film is that you could just read it on its surface, but I'm just delighted the way that people have responded. We try to put a lot of iceberg under the tip, as I like to say, and people sort of picking up on the stuff below decks, which is really great. You're to interpret it according to your own worldview. Obviously, there's ideas of how dominant hierarchies work, issues of resources, and how, in many cases, it's dominated by the powerful few at the expense of the many and environmental issues."

On the use of a female lead in the film:

"That feminist notion arose out of the mechanics of the story. An initial idea was to see, if the film was an extended chase, how much could people pick up on the run? And the notion being that what was in conflict was to be human, and it was five wives escaping a tyrannical warlord, and needed a female road warrior. It couldn't be male. So there was Furiosa, and the rest followed."

On the use of practical effects and real sets:

"This is a film that's a real-world film, that we don't defy the laws of gravity. In Fury Road, we don't defy the laws of physics. If you're going to have vehicles crash into each other in a desert, you know, why not do it for real? We have the ability as human beings to detect what's real or not. Particularly if you're doing things that you can at least see on television or YouTube that are actually real, you're going to be working very, very hard to do it all CG. There are no spacecraft. There are no flying humans. So it was the logical thing to do, and also everyone was up for it."

On the possibility of a sequel:

"The more I speculate about what's happening, the more I try to avoid spoilers this far out, and also I find myself talking around in circles. So the best thing I can say is that we're definitely in discussion about making more of these, but the timing of it, I'm really not sure. Probably won't be called Wasteland. I can say that. It was just the working title we gave it."

On Tom Hardy's involvement in possible sequels:

"We'll definitely see more of Tom."
