Mel Gibson and Danny Glover may be back together, as Warner Bros is toying with Lethal Weapon 5 again.

Since Lethal Weapon 4 was turned around in double quick time and proved a solid hit for Warner Bros in 1998, there have been constant rumours that stars Mel Gibson and Danny Glover, along with director Richard Donner, would reunite for one more outing.

Donner is keen to direct, with Gibson and Glover reprising their roles as detectives Riggs and Murtaugh, with Channing Gibson (Lethal Weapon 4) penning the script. Apparently all four are officially on board, should the project move forward.
