Kevin Blank was a Visual Effects Supervisor for Lost, who created the special FX seen on Lost, such as supernatural visual elements. He can be seen on the Lost: The Complete First Season (DVD) featurette Welcome to Oahu. Here, he is shown putting on "bear chaps", and playing a set of polar bear legs that were shot running through high grass, in the attack scene of "Pilot, Part 2". Soon after completing work on "The Brig", Blank stepped down as the visual effects supervisor, giving the position over to Mitch Suskin.
