Jesus Christ, Jim Jarmusch is 61 years old. The man who helped define the independent downtown New York film scene in the 1980s through the films Stranger Than Paradise, Down by Law, and Mystery Train can now get senior citizen discounts at Ben & Jerry’s. Maybe it’s telling that his latest, Only Lovers Left Alive, is about vampires. Not unlike his undead characters Adam (Tom Hiddleston) and Eve (Tilda Swinton), the strangely ageless Jarmusch (he still has that happy shock of white hair) has seen fads and movements pass by over the years. All along, though, he’s been whittling away at his own very idiosyncratic films, with their characteristic blend of melancholy and deadpan wit. Only Lovers Left Alive may be a vampire movie, but it’s more a love story than horror flick, more a meditation on poetry, music, and worldly experience than a story about fangs and blood.
