The Lord of the Rings: The Two Towers (2002)

In Peter Jackson's second installment of the Middle-Earth saga:

• the climactic and dramatic scene of the Battle at Helm's Deep, when Saruman sent his vast ten-thousands of troops (composed of monster warriors called Uruk-hai - Orcs cross-bred with Men) from Isengard to attack the small overwhelmed army of 300 (with bows and arrows) and destroy the world of Men; the archers were advised: "Their armor is weak at the neck and beneath the arm"
• although the situation looked dire and impossible, a last horseback attack into the midst of the enemy was led by King Aragorn (Viggo Mortensen) (to allow the women and children to escape on a mountain pass), bolstered by the arrival at sunrise of reborn Gandalf the White (Ian McKellen) (on his white horse) and Eomer (Karl Urban) (and his cavalry warriors) who then triumphed over Saruman's Uruk-hai/Orc troops
