I love this movie. One of my favorites, and I often quote it whenever I can. It's hard not to with lines like, "As you wish," and "That does put a damper on our relationship" and it is just overall awesome.
Well, one day while walking in a bookstore I saw the Princess Bride by William Goldman and I thought to myself. Why haven't I read you yet? So I picked up the book, bought it, and brought it home with me.
To which I read it in less than three days. I couldn't put it down. I LOVED it. It was fantastic. I laughed constantly, and fell in love with the characters more deeply. It was basically the movie with more detail and backstory. Which got me to thinking of all the book to movie adaptations out there.
Warm Bodies- Loved the book, and was excited to find out it was going to be a movie. Loved the movie, almost more than the book. A brilliant and wonderful adaptation.
Lord of the Rings/The Hobbit- I. Love. These. Movies. Like seriously, love them. And I love the books, (Well to be fair, I've only read the Hobbit back in Jr. High and the Fellowship. I'm halfway through the Two Towers. They are good books but dense) From what I've read, Mr. Jackson has casted it perfectly (PERFECTLY) and I love it when fans make things.
The Invisible- I really like this movie (it is sad, but good) and found out it was based on a book. Read said book. Didn't like it. So, this was one of the rare cases where I love the movie over the book.
Percy Jackson- I liked the movie when I watched it, but my sister suggested that I finally read the series. I am now a wholly invested fan of Percy Jackson and his adventures. The movie isn't bad, but it isn't the best either. The casting was fine, but they messed up some plot points and little details.
Eragon- Wait, they made a movie? (It was terrible, so terrible. The only thing they got from the books was the names and dragons. I tend not to think about it cause it was so heartbreaking awful)
The Hunger Games- I enjoyed the books (not a huge fan, but they were good) and the movie is great as well. There were minor changes but the got the gist and majority right. Casting was perfect though as was the costume and set designs.

Twilight-I admit it, I liked the books. The movies...disappointed. Seriously. Casting was mostly bad (sorry cast) and I just...I can't put my finger on it but it just didn't translate well to the screen. However, I did like the last movie a lot. Mainly because Lee Pace was Garrett who was my favorite character in the books (he totally deserves his own story...and yes I know you only meet him in like the last half of the book, I do not care, Garrett is awesome and amazing and I love him. And then they go and cast Lee Pace and I die of happiness) Ahem. Sorry...moving on.
Howl's Moving Castle- Yes this is a cartoon (tech anime but ok) but I LOVE THIS. I love Miyazaki's work, and Howl is my favorite hands down. It got me so curious that I bought the book, and though I love the book, Miyazaki basically took the characters and made them his own. They both have awesome merits but I suggest not comparing them, for you will enjoy both in different ways.
The Princess Bride- PERFECT. CASTING. WRITING. SETS. COSTUMES. EVERYTHING. PERFECT!
I understand why movies cannot be exactly like the books. I truly do, but I don't think it's an excuse to not try. Like the Princess Bride and Warm Bodies show it can be done.
