Even though there are a few differences there are also a few similarities. One of the biggest similarities are the father and son relationships. One way that the father and son relationships were similar is that in both, one was helping the other survive. An example of this is shown in Life is Beautiful when Guido convinces his son to go with the other German children. An example in Night is when Elie helps his father learn how to march, so his father is not killed. Another way that both relationships were similar is the fact that both dads would rather die themselves than see their sons die. Another similarity between Life is Beautiful and Night is the fact that both fathers die, while the sons stay alive. So those are just some of the similarities between the movie Life is Beautiful and the book Night.
Throughout the movie it is shown that life is beautiful, even through times of need and suffering. One of the most important examples of how Life is Beautiful is how Guido convinces his son that it's all just a game in order for him not to be scared. Another example is that when Guido is being taken to his death, he still plays along with the game. A final example of how life is Beautiful is when Guido and Joshua find the intercom, and they call her letting them know that Joshua was still alive.
An extreme difference between the movie, Life is Beautiful, and the book, Night, is the mood. Throughout the movie Life is Beautiful there is happy and humorous mood to it, while in the book Night it is completely different. An example how the mood’s are different because in the movie Guido makes it fun for his son making him think it was all just a game, while in the book there is just a bunch of death and torture. A final way that the mood’s are different is the fact that at the end Joshua has a happy ending reuniting with his mother, but in the book Weisel is basically all alone because most of his family has died.
