I saw the movie at an afternoon showing in the UK today and they very clumsily cut the scene where Aragorn decapitates Lurtz. I had previously seen it in Canada but those with me noticed the cut due to the jar in the music.

To be precise the scene cuts away the second that Aragorn stabs Lurtz in the chest straight to him running up to Boromir.

I don’t know if this was a one off by the cinema or this has happened all across the UK.
