It looks like the making of one 'Mad Max' sequel actually led to the conception of two more films!

'Mad Max: Fury Road' director George Miller recently spoke to Top Gear about how long it took to get the film in production, revealing that he had already started working on the movie back in 2001.

"This film [Fury Road] was green lit three times and fell over three times over a decade," Miller said. "We went to shoot with Mel Gibson back in 2001, but then 9/11 happened, and the American dollar collapsed against the Australian dollar close to 30 per cent, so we lost that amount of budget overnight."

The loss led to the shelving of the Mel Gibson version of 'Fury Road' and George Miller decided to take a different direction with his next project, an animated film featuring a bunch of dancing penguins. (Yes, he directed 'Happy Feet').

On his second try at 'Fury Road,' the desert got flooded.

"We were then rained out of Australia," Miller admitted. "The desert rained for the first time in 15 years, and we ended up in South West Africa, Namibia."

Despite all the trials, 'Mad Max: Fury Road' was ultimately completed, with a few extra stories that could lead to more sequels. George Miller revealed that the other 'Mad Max' sequels could glorify the vehicles in a different way.

"In this process, we had dug down deep into the backstory, not only of the characters, but of every vehicle. How the steering wheels became religious artefacts and things like that, so we ended up with two scripts, without really trying."

But which of the two new scripts could be the next 'Mad Max' film?

"We're talking to the studio [Warner Bros] about it as we speak, but which one of the two stories will happen next, I'm not so sure," Miller admitted.
