Kelly MacDonald in Trainspotting (1996)

No Country for Old Men (2007) is the latest one-of-a-kind big-screen blowout from celebrated filmmakers Joel and Ethan Coen, the sibling masterminds behind classics such as Raising Arizona (1987), Fargo (1996) and The Big Lebowski (1998). Tommy Lee Jones and Woody Harrelson head up the cast of this 1980-set tale of a drug bounty that brings nothing but bullet-riddled trouble to all who come across it. Co-starring are Josh Brolin, Javier Bardem and Scottish siren Kelly MacDonald. For a toot full of Kelly at her all-time most intoxicatingly naked, go score the similarly narcotic-driven cult favorite Trainspotting (1996). Twenty-five minutes in, Kelly drops her dress and hops atop Ewan MacGregor for some boisterous bedroom boinking. And that's one natural high … actually, it's two.
