Sam Worthington in Wrath of the Titans (2012)
WHO ARE THEY: Beregond was a member of the Tower Guard, an elite unit of Gondorian warriors, charged with protecting the Citadel of Minas Tirith. Bergil was his older son.
DURING THE WAR OF THE RING: Beregond was assigned to help the newly-promoted Guard member, Pippin Took, to get acquainted with the city. He also defended a badly wounded Faramir from Denethor burning him alive, and later fought at the Battle of the Black Gate. Bergil quickly became a good friend to Pippin, and ran the errands in the city (such as finding athelas for Aragorn), after the Battle of Pelennor Fields.
AFTER THE WAR OF THE RING: Beregond and Bergil moved to Ithilien, where Beregond became the Captain of Prince Faramir's guard.
