I just got home from seeing the movie adaptation of Under The Mountain. It is a must see. It remains very true to the book with only a few minor changes (such as the age of the twins). The entire production is top notch, the acting and cast is perfect, the special effects state of the art (thanks Weta Workshops) and it is great to see such a good kiwi film. I will note that the film, while based on a kids book, is rated M, it is not over the top scary. But it is scary enough that it would easily upset some kids (even some adults jumped in parts of it). It would be the best kiwi film since Out of the Blue.
