The pic comes courtesy of Indiewire, who describe the film as eh story of Adam,
"an underground musician who's deeply depressed by the direction of human activities. He reunites with his centuries-long lover, Eve (Swinton), though their idyll is soon interrupted by Eve's wild and uncontrollable younger sister Ava (Mia Wasikowska)".
Only Lovers Left Alive also stars John Hurt and Anton Yelchin, and doesn't have a release date yet. Something tells be that this being a Jim Jarmusch movie we shouldn't expect too much blood n gore, or even that it will necessarily be a horror film, but I look forward to it nonetheless.
