“The Sorcerer and the White Snake” does what so many fairytale romances--“Twilight” and “Warm Bodies," to name a few--don't: it goes big. This 2011 Hong Kong film by Chinese choreographer and action director Ching Siu-Tung a.k.a "Tony Ching," recounts the story of a demon--actually a white snake with the seductive head and shoulders of a woman (Eva Huang)--who falls in love with a poor herbalist (Raymond Lam)
