'The Lord of the Rings: The War of the Rohirrim' review: What if Éowyn got her own movie?
Sound familiar? That's because the story of Helm Hammerhand is basically the prototype for The Two Towers ' Battle of Helm's Deep. After all, he's the reason the Hornburg comes to be known as Helm's Deep! Yet The War of the Rohirrim is no Helm's Deep retread. It's a brutal, lengthy siege that pushes everyone involved to new, desperate limits.
