17. MALCOLM McDOWELL
A Clockwork Orange (1971)

Who knew milk and Beethoven could be so downright disturbing? Throw in a bowler hat and cane, and you have one of cinema's most indelible images of apathetic evil — an image brought to life by McDowell in Stanley Kubrick's masterpiece of ultraviolence. But McDowell was more than simply a visual (and virulent) centerpiece. As ruthless hooligan-turned-aversion therapy patient Alex, he ran the emotional gamut — delivering riveting portrayals of both sinister charm and helpless dread.
