DIFFERENCES BOOK AND FILM: FRANKESTEIN

We read the book Frankestein, and then, we also watched the film, comparing both versions, there are many differences.
At the beginning of the film, the creature isn't moving on a sledge, and in the book he's on foot.
In the film, Victor has only got one little brother, William, who dies, but in the text appears another one, Ernest.
Apart from that, Victor's mother dies in different ways: in the book it's because of an illness and in the film giving birth to William.
Victor's relationship with Henry Clerval is different because in the book they've been friends since they were in school, and in the film they don't meet until university. In the book, Victor's laboratory is far from the university to keep the secret, but in the film, a lot of people can enter the laboratory, for example Elizabeth, who visits Victor because she's very worried.
In the film, the monster collects vegetables from the family that lives next to them, but in the book, it helps the family by cutting firewood during the night.
After Justine was accused of killin William, in the film she is hanged, and in the book she was in prison and she dies here.
In the film, the monster kills Elisabeth on her honeymoon by pulling out her heart and then, it wants the body or Elisabeth for its wife; in the book, it strangles her. Frankestein can give life to Elisabeth, but she burns herself.
Finally, the end of the story is different, because in the book the monster dies alone, walking on the ice, but in the film, there is a more emotional ending, because the monster dies next to Victor's Frankestein.
In my opinion, it is good to read the book and agterward watch the film, because if you do not understand something of the book, is easy to understand it by watching the film. I also think that is difficult to make a composition with the differences of both, because there's a lot of differences, for this reason, there aren't all teh differences in the composition.
