I watched the movie A Tree Grows in Brooklyn (Import, All Regions) and loved it. So when I found out it was based on the book of the same name I naturally read A Tree Grows in Brooklyn (P.S.). And loved it even more.
I often find that I like seeing a movie and then reading the book it was based on rather than the other way around. Most movies don't do justice to a good book not because they don't try, but because a book has the opportunity to expand on the characters and story more than a movie can.
But to see a movie and fall in love with the story and/or characters and then find that you can go into greater depth by reading the book I find to be a wonderful experience.
What movies have you seen that lead you to read the book? Did you find it a more rewarding experience after having seen the movie?
