4. Dirty Harry vs. The Scorpio Killer - Dirty Harry
How could I not include Harry Callahan's first movie outing? Here he finds himself chasing down the tricky serial killer Scorpio - based on the real-life Zodiac killer who similarly terrorised San Francisco - and the entirety of Don Siegel's classic movie builds perfectly towards this chase, in which Harry finally has his man. With Scorpio wounded on the floor, Harry lets out with signature snarl, "I know what you're thinking. 'Did he fire six shots or only five?' Well, to tell you the truth, I forgot myself in all this excitement. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself A question - 'Do I feel lucky?' Well, do ya, punk?" Scorpio responds by reaching for his gun, prompting Harry to blow him away, having a nice, long fall into the water, dead. Totally badass.
