"I've seen the sparkle scene on Blu-ray, and it looks really great. I was worried how that would translate." Not entirely satisfied with the results of the sparkle effect tests she saw from several FX facilities, Hardwick decided to take matters into the best possible hands, ILM, and is hoping that they go back in and take advantage of the Blueray technology.
"We are looking into to going back to ILM and pushing that scene a little further for the Blu-ray disc. We have about a dozen deleted or extended scenes to put on the DVD, and I made a couple crazy montages of all the times the vampires kiss or attack someone and of all the human hijinx, and I've done a visual remix of the movie for the DVD also."
