Popular Mechanics on Special Effects Used in Half-Blood Prince

HBP Film

Popular Mechanics has a new article online today that gives some new insight regarding the special effects used for two scenes in Harry Potter and the Half-Blood Prince done by Double Negative. As seen in the many trailers and clips from the film, HBP features an attack on the Millennium Bridge in London, England to showcase the rampant actions of the Death Eaters, as well as the Inferi in the cave. While there are movie spoilers contained in the article, the piece does contain technical info on how the scenes were created with legendary VFX house ILM:

"Once modeled, the Inferi went to a painter, who laid down the creatures' color and texture, while another designer put a skeleton inside the Inferi model to make it move. Next, animators began motion tests. Because Yates wanted to avoid zombie cliches, ILM spent a lot of time researching the movement of the Inferi. "It really came down to their expressions and movements to keep them out of zombie land," Anderson says. Yates cast actors and filmed their movements using motion-capture technology, which was eventually combined with hand animation, to create the Inferi's final movement. "Not having them groan and stick their arms out gets you away from the zombie look," Anderson says. Animators used an in-house software called Zeno to animate the Inferi crowds and the flocking above and below the surface of the lake.
Creating the Inferi scene "was extremely challenging work," Anderson says. It took six people 45 weeks to create the Inferi; once they were created, the team needed 25 more artists to complete the necessary shots. The final result? Two very impressive minutes of screen time."

Related: The New York Daily News let us know about some cool pics they have of work done by ILM  creating special effects for various blockbusters, including this of the Inferi for Half-Blood Prince, as well as Dobby in CoS.

The special effects that can be made today never cease to amaze me… it truly is awesome how much work is put into stuff like that, which may be only on screen for a few minutes.
