Jon Huybrecht directed "Harvest," about revenge from beyond the grave. We helped Jon add some extra horror with a few visual effects that would have been impossible to get in-camera. Jon isn't an expert firefly trainer, so we created these fireflies on the computer. We didn't just want little yellow dots floating around, so Dave Codeglia modeled a 3D firefly with fully functional wings, torso, and antennae. Some shots have over one hundred insects flying around. One even had to land on an actor's forehead.
