While watching The Hours, my brain immediately began linking the characters in the movie to characters in the book. In many characters in The Hours I noticed many aspects from each character in Mrs. Dalloway. For example, within Richard, I could identify the obvious connections with Septimus (the suicide and his "insane" attitude), but also with Peter (his history with Clarissa) and Virginia Woolf herself. While there were minor differences in details such as Clarissa being married to Sally rather than Richard, I found the most shocking difference to me was the tone of The Hours versus Mrs. Dalloway. In the novel, Clarissa seemed reminiscing on that particular day, but she didn't seem sad. She was merely thinking about the past how different her life might've ended up, and throughout her day she went through ups and downs. However, in The Hours, by incorporating Virginia Woolf's own experiences, I think the movie took a more obvious look at the meaninglessness of life (also a theme of Mrs. Dalloway and portrayed their lives in a more lonely way.
One big aspect that the movie used to develop this more bleak look at life was through the suicidal thoughts of more than just one character. In the novel, the only character that has a huge yearning for death was Septimus, and at the end Clarissa. However, in the movie, Richard, his mother Laura, and Virginia Woolf all either committed suicide or came very close. I think that fact that the three plots inside of The Hours were mainly connected by this fact really tied in the notion of the meaninglessness of life, and showed how certain people started to feel alienated by everyone around them because they just couldn't bear to be alone in the world. Not alone in the physical sense (because Virginia, Laura, and Richard all had someone who really loved them), but that no one understood them. The Hours really made me think about this and I think that fact that I knew a background of both Woolf and the novel, made me really enjoy the movie.
