#4: “I Know”
The Star Wars saga is beloved for its mix of classic heroism, political drama, and fantastical beings. The Empire Strikes Back stands out, enriching the lore with unforgettable scenes and quotes, notably an improvised moment by Harrison Ford.

In a pivotal scene, Leia professes her love to Han Solo, who was scripted to reciprocate. Harrison Ford, feeling this out of character, improvised with a simple “I know.” This iconic exchange, encouraged by George Lucas, became one of the saga’s most memorable moments.
