Continuity mistake: When Jim's car approaches the beggar on the sidewalk, in the wide angle Jim is sitting on the far right. In the close-up he is sitting on the far left.
Continuity mistake: Jim passes twice by the same part of the Gone with the Wind poster.
Continuity mistake: When heading for the costume party, when Jim leans to see the crowd, his hand is on/off the car's window.
Chosen answer: The first time, Jim says "Nanika no machigai desu. Bokutachi wa minna tomodachi desu yone. Senso no sei desu." This roughly translates to "There has been some sort of mistake. We are all friends aren't we? It is the war's fault." The second time, Jim only says "Nanika no machigai desu. Bokutachi wa minna..." and then gets pushed aside. "There has been a mistake, we are all...". I hope that helps.
