Although there's been a slate of consecutive flops in the YA book to film genre, the first real test will come with 'Divergent', which comes out next year. Divergent's often been called the 'next big thing', and compared favorably to the Hunger Games, and the number of book sales certainly stack up [although not nearly matching the Hunger Games].
The first full-length trailer for the film was officially released at the VMA pre-show this weekend, and it was very well received by most fans of the books. The film mainly give us a look at the action, and keeps the world-building to a minimum. The fact that Shailene Woodley's character, Trior Prior, is 'divergent' is really highlighted, although it's not fully clear what divergent means for those who haven't read the books.
In addition to seeing Shailene and co-star Theo James' 'Four', we also get a glimpse of Kate Winslet and Maggie Q, and the visuals definitely look much better than they do in most YA film adaptations.
'Divergent' stars Shailene Woodley, Theo James, Kate Winslet, Zoe Kravitz, Maggie Q, Miles Teller, Aaron Eckhart, Ashley Judd, Jai Courtney, Ansel Elgort, Ray Stevenson and Tony Goldwyn.
