Time Warner Cable's ads that purport to really bring you into the TV show you're about to watch aren't all that engaging usually, but this new one, for HBO's "True Blood," is a treat to watch. Created out of Ogilvy & Mather and directed by Nicolai Fuglsig, out of MJZ, the beautifully shot, blood-spattered commercial will either have you watching horror-struck or licking your lips in anticipation--and there's a lip-smacking cameo in the end from the show's Deborah Ann Woll, who plays young vampiress Jessica Hamby. According to the press note, the raining blood was pumped in, with lots of research taking place to make sure it had the right viscosity of real blood.
