In the extended edtion DVD there is a making of disc that shows a deleted scene of aragon fighting souron at the black gate but it was cut out and changed so that he fights a troll instead.
As Aragon looks up towards the enemys souron appears in his true form as a glowing white man then his armour appears on him and he fights against Aragon.
Just want to hear your thoughts on this and if it should have been left in the film.
