Mel Gibson and Danny Glover are back as unlikely cop partners Riggs and Murtaugh in this blistering all-action sequel that's marginally the best of the four Lethal Weapon movies to date.

This time they tangle with evil South Africans running drugs under the shelter of diplomatic immunity.

Look out for Emmerdale's Patsy Kensit as a good South African, along with a song from her band Eighth Wonder.

Mel Gibson's character Riggs was meant to die, but in the finished film he is only wounded so the series could continue.
