How Jackson's Eye of Sauron Transforms Frodo's Journey

Adapting The Lord of the Rings required Peter Jackson to balance fidelity to Tolkien with the demands of cinema. While he kept many story beats and lines, Jackson also added a major storytelling element that does not exist in the novels. In the book the Eye of Sauron functions as symbolism rather than a literal organ.

Sauron’s physical form was destroyed and, though he later repairs a humanoid presence, Tolkien mostly lets him operate from the shadows. The Eye serves as a metaphor for his ubiquity and the reach of his evil influence. Jackson makes that metaphor visible. The films place a giant, lidless Eye atop Barad-dûr that emits a red beam across Mordor, giving Sauron a constant, watchful presence.

That tangible gaze amplifies anxiety and surveillance, reshaping Frodo’s mission on screen and making the quest feel more perilous and urgent. The trilogy shows the Eye tugging at the Ring in Galadriel’s Mirror; Frodo encounters it when he puts on the Ring to enter the wraith-world, and Gandalf briefly spies it when he touches the Ring.
