Heath Ledger and Jake Gyllenhaal in Brokeback MountainBROKEBACK MOUNTAIN

In Ang Lee's agonizingly fine romantic western Brokeback Mountain, two taciturn young men - Ennis del Mar (Heath Ledger) and Jack Twist (Jake Gyllenhaal) - are hired, in the summer of 1963, to tend flocks of sheep on a Wyoming expanse. During the early days of their tenure, the men barely speak. Yet as the months pass, they form a solid friendship, and on one particularly cold night atop the mountain, Ennis and Jack share a bottle of whiskey and a sleeping bag, and - experiencing wordless, nearly aggressive desire - have sex. Despite the inevitability of the encounter, the sheer, naked hunger of the scene is startling, but a greater surprise comes some 20 minutes (and four years of screen time) later, in a scene so powerfully, emotionally true that - like much of Lee's transcendently moving work - it hits like a slap in the face.
