The characters use irony throughout the movie because we know what happened in the concentration camps but the characters in the movie don't. An example of this is when Joshua refuses to take a shower because he doesn't like them and refused earlier in the movie. We know that if Joshua had taken that 'shower' he would have been gassed and been out of the whole movie. Whats ironic about this is because they take advantage of Joshua being a stubborn kid and not wanting to take a shower which actually saves his life.
Another way the characters in 'Life is Beautiful' represent and engaging and unique presentation on the Holocaust is by setting the movie in the Jews perspective. By showing what it was like to be in a concentration camp from the Jews perspective, we get a real sense on empathy and we feel bad for what they all had to go through in World War II. By showing the movie in that perspective instead of the German side, we get more of an understanding of how deep and depressing this situation was, which makes the movie more interesting and engaging.
The third reason for how the characters make this movie engaging and unique is because the use of close up shots and individuality we get a real understanding of the types of people they are. From the very beginning we find out Guido is a funny person and tries to do whats right and thinks on the positive side of situations. Later we find out that he is a loving father that is trying to make the Holocaust as good as he can for his son Joshua. Joshua represents the innocents in the Holocaust and how so many kids we killed due to the fact of being a Jew. Through the whole concentration camp half of the movie the audience gets engaged at him not knowing whats actually going on and how much we hope he survives. We also develop a sense of knowledge from the doctor that loves riddles. In the beginning he comes across as a man that just loves riddles, but when we find out he is also on the German side of the Holocaust we realise he doesn't think the Holocaust in a big deal and ONLY cares about riddles.
They are the three main reasons for how the characters in 'Life is Beautiful' represent and engaging and unique presentation of the Holocaust experience.
