http://moviemikes.com/category/interviews/ for a whole heap of interviews with practically everyone in the MK cast

Check out the Shane Warren interview for which Mortal Kombat (comics) character is appearing in this series who will also be played by Shane, and the identity of the blue motion capturing suit in one of the videos

Also the interview with Michael Rogers said he originally auditioned for the role of Kabal.. (so maybe that is a character on the cutting room floor.. introducing him to set up his back story for series 2?)
