Need explanation for the few scenes
In few scenes I saw some details but I couldn't get them. If someone can explain.
1)
In scene in Major Major's office when his tell Sergent who and when to let see him and before he sneaks out the window, picture on the wall is changed 3 times(Roosevelt(or Truman), Churchill and then Stalin). I'm not sure that I quite get it. Is it about things he is talking while each picture is there, to explain each leader or something else?
2) On the end of scene when he is acting as a dying soldier in front of his family through the window u can see the extremely blue sky in big contrast to the room. Does this also have some meaning or it's only for visual effect?
