I recently watched the movie
Apocalypse Now, and I thought it would be an appropriate one to discuss for this assignment.
Apocalypse Now
During the Vietnam War, the young American Captain Willard is given the assignment to hunt down and kill one of his own: Colonel Kurtz, who has apparently gone insane, murdered hundreds of innocent people and constructed a strange kingdom for himself deep in the jungle. Willard and his crew embark on a surreal river journey to find Kurtz. One famous scene shows a beach attack where the helicopters are playing "Ride of the Valkyries" as they approach. This is a war movie, but I think that it is more about how war changes people. It goes into the darkness that they can experience because of war.
^The helicopters approach while playing the song as loud as they can.
Apocalypse Now and Slaughterhouse-Five are very different, but there are still some similarities. In my opinion, they are both somewhat about the horrors of war. Though not explicitly showing this, they both have elements showing how people change due to what they experience in war. Mary O'Hare would probably be okay with this movie because it doesn't glorify war as much as it just shows what goes on and people's mental and physical reactions. If you haven't seen this movie, you really should. It is bizarre in some ways but it is one of my favorite Vietnam films.
