Jemaine Clement and Taika Waititi Are Onto Something PARK CITY, Utah - Vampires have finally descended on Sundance. In its 30th year the festival may be, as Manohla Dargis writes more vital than ever to the indie film scene. But that doesn't mean it's immune to the lure of big thrill entertainment that the undead provide. This year's festival had not one but three vampire flicks: the high-profile "Only Lovers Left Alive," from Jim Jarmusch, starring Tilda Swinton and Tom Hiddleston; "Girl Walks Home Alone at Night," billed as "cinema's first Iranian vampire western;" and "What We Do in the Shadows," from writer-director-stars Taika Waititi and Jemaine Clement. Mr. Clement, best known as half of the Flight of the Conchords comedy team, and Mr. Waititi, a filmmaker whose credits include "Boy," set their movie in the ghostly scene of Wellington. "We wanted to explore the issues facing the undead community in New Zealand," Mr. Waititi said. Not only vampires but also werewolves, who are living but they sill have an undead kind of affliction. Zombies, witches - "The supernatural beasts," Mr. Clement added. "And what life is going to be like for them in the future," Mr. Waititi said. "Life after death," Mr. Clement said. Undeath. They had the idea long before "Twilight," they said, in an interview on Main Street here. "This is going to make vampires cool, I think, this film," Mr. Clement said with confidence.
