Presaging a day when long-dead Hollywood film stars can be resurrected by digital wizardry, the special-effects house Framestore Digital has created a commercial for Galaxy chocolate starring a digital version of Audrey Hepburn, who died in 1993 at the age of 63. On its website, Framestore said that it first attempted to alter the facial features of a model who resembled Hepburn but were unhappy with the result. The effects team, it said, realized that full CG was the only way to get it right. A casual viewer is not likely to realize that the image of Audrey Hepburn in the commercial is created by effects artists, but those who are aware of the process will no doubt notice the flaws. Although Hepburn's name is not used in the commercial, the company said that it negotiated with her estate to use the computer-created image. Commenting on the commercial, TheVerge.com said on its website, If the success of a commercial is measured by the number of heads it turns, then Galaxy chocolate's latest ad is nothing short of triumphant.
