Have you spent the past few months wondering how the heck you’ll be able to safely dress up as “the girl who was on fire” for Halloween? Well, this exclusive bonus feature clip from The Hunger Games Blu-ray and DVD set (due out Saturday, August 18) might help. Proving no detail is too small when you’re in charge of adapting a mega best seller into a mega blockbuster, director Gary Ross and visual effects supervisor Sheena Duggal explain how they mastered Katniss and Peeta’s memorable “firewings” effect. Apparently, it’s a process that included several rounds of concept art; hours of debate; and a digitally rendered naked, bald, and areolae-less Josh Hutcherson. May the bod be ever in your favor, indeed.
