On the one hand, this Chinese Johnnie Walker commercial featuring a CGI Bruce Lee (from "Torque" amd "Detention" director Joseph Khan) is creepy in the way that dead people "endorsing" products generally are. On the other hand, if there's any celebrity living or dead for whom it can be argued that their cultural presence as a "mythic figure" has so transcended their actual existence that something like this isn't really that much more "offensive" than Santa Claus selling Coca-Cola... I guess Bruce Lee would be it.
Either way, it can't be denied that the effects used to pull this stuff of, while still not "there," are really close to getting "there." I wonder who the first celebrity will be to "star" in an (otherwise live-action) film as their own years-younger self? It's not that far outside the realm of possibility for a studio to say "Y'know who would've been good in this? Bruce Willis, but like ten years ago Bruce Willis..." and for Bruce Willis (or whoever) to just do the mocap and voice work for that.
