But if we were to include television, I'd go with Twin Peaks. Bob's reflection in the mirror...
You mean the 'I ain't so tough part', or what happens after?
What happens after. The song, I'm Forever Blowing Bubbles, plays on the Victrola phonograph when a phone call to the Powers home reports that Tommy is coming home. His mother cheerfully goes upstairs and hums to herself as she prepares his room for his home-coming: "Oh, it's wonderful. I'll get his room ready. I knew my baby would come home." In the rival gang's gruesome plan, Tommy's bullet-ridden, rope- and blanket-wrapped 'mummified' corpse/body is gift-delivered by a knock on the door. When Mike answers the front door, Tommy appears alive, bound from head to foot except for his exposed, bandaged and bloody face. It is the film's final memorable bone-chilling image - he tetter-totters on the doorstep, and then his mummy-body falls and crashes with a dull thud - face-first onto the floor. The needle on the revolving phonograph record becomes stuck, sounding like a heart-beat. Mike examines the body of his brother - and then stares into the camera. Filmed from ground level and from the waist-down, he slowly and steadily walks toward the stairs in the interior of the house, presumably to tell Ma. The needle reaches the end of the record. The film's somber message appears over the image: The END of Tom Powers is the end of every hoodlum. 'The Public Enemy' is, not a man, nor is it a character -- it is a problem that sooner or later WE, the public, must solve.Ahh, they don't make em' like that any more!
Two more excellent endings spring to mind: PLANET OF THE APES (original of course) and the wonderful LITTLE CAESAR!
