Khan in 'Star Trek Into Darkness'

Khan had Cumberbatch turning up the heat in space—as if space needed more drama! His Khan is pure ice-cold villainy wrapped in a voice that could sell fire in hell. Fans argue whether he's the best Trek villain as fiercely as they fight over the last slice of pizza. Yes, he made you empathize with a man who could crush skulls just by thinking about it. That's Cumberbatch for you: making us cheer for the bad guy and feeling guilty about it later. Classic Benedict betrayal!
