The film was released in 2013 and it was directed by Andrew Niccol it’s an adaptation of Stephanie Meyer’s book. So it’s the same story without some details present in book.

I’ve read the book and watch the film and to my opinion it’s a good adaptation even if I prefered the book. I found the story interesting and I really liked read the book, so one day if you can reading it and like sci-fi,I advise you to do so.
