It's been nearly 14 long years since 'Lethal Weapon 4' came out, and while there was always talk about a fifth installment, it never came to pass. But now director Richard Donner has spoken out about what could have been if cameras had rolled on 'Lethal Weapon 5.'

The new issue of Empire magazine is celebrating the 25th anniversary of the first 'Lethal Weapon' by bringing together Donner and his two stars, Mel Gibson and Danny Glover, for a walk down memory lane about the buddy cop movie that pretty much defined the genre. While the full interview is just hitting shelves in the U.K. now, Empire Online has printed an excerpt in which Donner and Gibson discuss the unfilmed fifth movie.

Asked if there were any ideas for a fifth film, Donner says, "Lots. There was a fifth one that I would have loved to have made. Shane Black wrote another treatment, which I never saw..." Gibson adds, "I saw it. I saw everything."

But Donner says he had a sequel idea of his own, continuing:

"We had a totally different story. The two crazies decide to cool their lives, but it's impossible for them to stay out of situations. It starts with Riggs and Murtaugh out in the country in a motorhome. They're on a trip and they stop to get gas, but Roger forgets to put the brake on. So the motorhome rolls through a village, annihilating everything, and they get in serious trouble. It had a lot of heart, a lot of family. Rene (Russo, who played Lorna Cole), Darlene (Love, who played Trish Murtaugh), they would all have come back."

We're not exactly sure how that scenario might have turned into an action-packed crime thriller, and isn't "a lot of heart" and "a lot of family" what started to bog the series down? In any case, we'll never know now, but would you have wanted to see a 'Lethal Weapon 5'? What should they have done with it?
