Amazon's Lord Of The Rings: Fan-Casting Every (Possible) Major Role

The unsure daughter of Rohan requires an independent ingenue on the brink of realizing her strength. With her sweet face but daring nature, Fanning could help shape any origin story for Eowyn with ease and she perfectly matches the physical description of Theoden's niece.

Miranda Otto gives a compelling performance as the woman who defeats the Witch-King. Before she faces the villain, Eowyn grapples with the weakened state of Theoden's kingdom. It's empowering to witness Eowyn's escalating confidence in the latter half of the trilogy.

Likewise, the ascension of Fanning's Princess Aurora in Maleficent from waif to sympathetic royal is a glorious example of fearlessness. Aurora listens to her conscience, allying herself with her father's enemy. Fanning would have no trouble interpreting Eowyn's kind and willful spirit if her take on Aurora is any indication.

The Beguiled star is nearly six feet, befitting for the White Lady of Rohan. Tolkien describes her as "tall and slender." There's plenty of possibilities with Eowyn in the spin-off. Her courtship with Faramir could produce many new storylines since their love story was brushed over in the films. Fanning's no stranger to performing love scenes, and Rings fans could finally see Eowyn in a mutual romance.

Fanning also happens to be a horseback rider like Tolkien's female warrior. An advocate for sanctuaries for wild horses, Fanning's love for Rohan's trademark animal would be a heartfelt addition to Eowyn if she mounted up for the series.

The impact of Eowyn's courage should continue with Fanning sitting in the saddle.
