That sense of darkness is demonstrated by the Queen's specific goal in the story: To eat Snow White's heart. That darkness accompanies a whole lot of action, with no shortage of slow-motion shots, often featuring people or objects shattering into bajillions of pieces. The shattering motif continues right up until the very end, as the Queen shows off some magical powers.
The influence of Peter Jackson's take on The Lord of the Rings is obvious in the look and feel of this particular fairy tale world. While it's certainly more overtly magical than Middle Earth, it is defined by the same sort of textural griminess and rough edges. Rupert Sanders, a visually-minded commercial director whose work you've no doubt seen many times, makes his directorial debut here, and it looks like he has something to prove.
Stewart, Theron, and Hemsworth anchor a cast that also includes Sam Claflin, Lily Cole, Bob Hoskins, Eddie Marsan, Ray Winstone, Vincent Regan, Nick Frost, Toby Jones, and Ian McShane.
Snow White and the Huntsman arrives on June 1st.
