At any rate, it occurred to me that all of those movies had been based on books. And while I'd read The Hobbit years ago, I haven't yet read Cloud Atlas or The Silver Linings Playbook. Now, having seen the movies, I'm ready to check out the books.
So what's your preference? Do you prefer to read the book and then see the movie (which may change things, add things. alter or eliminate characters and certainly won't include everything in the book)? Or...do you see the movie and then read the book (in which case, your vision of what's going on and how things appear may be influenced by what you saw on the screen)?
For me, I think it varies. If it's a love story (Jane Eyre, Pride and Prejudice), I definitely want to read the book first. That rarely spoils the movie for me (I could watch the many versions of Pride and Prejudice over and over), but some movie interpretations of love stories would leave me less inclined to read the books, meaning that I would have missed out on a lot of wonderful books (i.e., if I don't fall in love with the movie hero for whatever reason, I'm then nervous about meeting that same hero--possibly a wonderful hero--in book form). So yes, if it's a love story, definitely book first.
But in some cases, outside of romance, I almost need the movie to pique my interest. In such cases, I consider that a bonus. I get to see a good movie and that leads me to a great book and broadens my reading horizons.
