My dad is a huge J.R.R. Tolkein fan and I was talking to him about FYS and he mentioned how there’s a dam removal scene in the two towers film that I completely forgot about. The dam removal in the movie is used to drown the orcs. I thought I was interested after seeing those videos of dam removals how the movie used it for the dramatic scene.
