Now, tag lines are it. For years copycat videos have ripped off the titles of famous theatrical releases. But for the first time in memory, an advertising slogan — ”Love never dies” from Bram Stoker’s Dracula — has spawned two knockoff phrases. ”Lust never dies” (from cheapie horror flick Savage Lust) takes the most literal liberties with the original, though the synonymous flair of ”Passion is immortal” (from Roger Corman’s Dracula Rising) hews more closely to its spirit. If you’re going to steal, might as well do it with style.
