Irolas was an officer on Minas Tirith in Peter Jackson's The Return of the King. He is played by Ian Hughes.
Irolas appeared after Faramir had pulled out of Osgiliath, and had a few appearances afterwards. He does not appear at the pyre of Denethor or the coronation of Elessar.
In the commentary of the Extended Edition of The Return of the King, it is stated that he was originally to be called Beregond, but as the role was reduced, Peter Jackson saw little use in still calling him Beregond.
On the Decipher Card, Irolas is identified as Imrahil instead.
