That four-alarm explosion in the opening sequence of Lethal Weapon 3 is a mere campfire compared with the sparks that fly when Lorna Cole and Martin Riggs (Rene Russo and Mel Gibson) start comparing scar tissue. The sexual tension mounts as the two take turns peeling back denim to display old bullet wounds in a competitive peekaboo. Refusal to acknowledge Riggs' piece de resistance-a scar that leaves him stripped down to his tight, black BVDs-leads to a skirmish, which leads to a long, hard kiss. But Cole is still determined to come out on top. So she uses her martial artistry to put Riggs in his place: beneath her in a sexy tangle on the hard, wooden floor. Ka-BOOM.
