Answer:
1. The viewer should pay attention to the way Atticus speaks. His body language and his words are an emphasis on what he believes in. You focus on the act of serving justice in the courtroom.
2. Atticus is very sad about what is going on and is trying his best to defend Tom Robinson. He knows that Mayella and her father are in the wrong and you can tell that he is very nervous about the outcome. He might not be able to save Tom's life.
