Director George Miller recently spoke to a news station in his homelands of Australia and discussed his new sequel, Mad Max 4. Miller talks briefly about the project, how he’s going about casting it, and also shows off some of the brutal post-apocalyptic vehicles that are being built for the movie. Unfortunately, they don’t really show the cars, but you do get a decent peek at them and an idea of what to expect.

Miller explains that the vehicles have to be incredibly high-performance to accomplish the shots that they need, but that they also have to be very safe for all the insane stunts that Miller promises will be used. Because of this, he says that it will take about a year to fully construct them all and that this extended time period is also to ensure that they raise the bar considering how much things have changed over the past 30 years in both action movies and film making in general. He then moves on to casting and admits that they’ve been “furiously” going about the process, but that he still has no idea who will be involved yet. One reporter even asks if Mel Gibson will be involved to which Miller responds “everyone’s an option.” It’s highly doubtful that Gibson will be involved, but it’s always fun to keep the hopes alive.

OK, while it’s not 100% guaranteed never ever to happen, it does now look like we won’t be seeing Lethal Weapon 5.

As you may recall, producer Joel Silver was just waiting to hear back from Mel Gibson and it appears that Mr. Gibson was heard from. The LA Times spoke to Lethal Weapon‘s first director Richard Donner, who said said that Gibson is a no-go.

It looks like the only one thing keeping Lethal Weapon 5 from moving forward at the moment is Mel Gibson and his seemingly hard-to-obtain blessing.

Shane Black — who wrote all previous Weapon films (and The Monster Squad!) — has written the 5th movie’s script and is hoping to direct after successfully writing and directing the extremely entertaining Kiss Kiss Bang Bang.

All things now rest in the hands of Gibson himself and whether he wants to step back into those shoes again. My presumption is that it won’t be too long before he gives the treatment a run through and decides, but you never know.
