"We came up a bunch of concept designs and I passed those on to Hybride because what I wanted to do prior to actually shooting the control room was to create animation that had some information about the performances of the actors," Duggal says. "So Hybride created these animations that allowed us to inform the actors even though we didn't know what the content was going to be at that time. And when we got into post, Gary had some very specific ideas about what the graphic content on those desktops should look like, so they worked with us in creating those holograms and their functionality. We went through the whole movie with them and what's happening in the story and during the games."
Hybride used a combination of 3D and 2D and turned the main hologram into a 3D model that represents the arena; then using the mesh from that in Flame they created some 2.5D effects. The concept is that the graphics are made up of data that's organic and alive, which then comes alive in the arena in the form of the fire or the mutts.
Judging by the phenomenal success of "The Hunger Games," it's a good bet that Duggal will be back to work on the two sequels adapted from Suzanne Collins' popular Scholastic book trilogy: "Catching Fire" and "Mockingjay."
