HBP VFX behind-the-scenes feature

If, like me, you are interested in how the Potter films are made, this ones for you...

Rising Sun, the special effects company partly behind the Harry Potter film franchise, have released a look at the visual designs used in Half-Blood Prince. Computer graphics implemented to digitally alter scenes involving Harry and Dumbledore's visit to Slughorn's home, the Weasley twins' joke shop, Draco's injured and bloody body when struck by the Sectumsempra curse, and Snape and Draco leaving Hogwarts at the end of the film.
