The franchise reboots may never end. According to ComingSoon.net (who spotted it on TrackingB.com), Shane Black has written a spec script for Lethal Weapon 5 without really telling anyone but Joel Silver.

The story would center around Riggs' impending retirement (and his, undoubtedly, being too old for ... well, you know). But before he leaves the force, he has to tackle one last case, and as there are no other police officers in Los Angeles, he hauls Murtaugh out of retirement to help him. Allegedly, both Mel Gibson and Danny Glover are interested, though no deals have been signed.

Now, I name drop Lethal Weapon enough that you undoubtedly know that the series ranks much higher in my life than it probably should. Watching it in my pre-teens not only taught me a choice vocabulary, it rocked my world with glimpses at a naked Mel Gibson. My problems with men probably stem from the pedestal I have placed Martin Riggs upon.

But, that doesn't mean I want a fifth movie -- I already sat through the fourth installment, and it wasn't that good. Black has penned some fantastic scripts in his time -- and I firmly believe A Long Kiss Goodnight is insanely underrated -- and I'd love to see him churning out action-comedies again. But not ones with Riggs and Murtaugh. Let Lethal Weapon lie, and write a franchise that can give us a new badass or two.
