Filmmaker Drake Doremus makes films about impossible love; difficult, complicated, bruising, fragile love. His latest, "Equals," leaves behind the realistic contemporary environments of his two previous features, "Like Crazy" and "Breathe In," for a sterile, dystopian future, but the emotional issues remain the same. Starring Nicholas Hoult and Kristen Stewart as the star-crossed lovers, "Equals" is a riff on "Romeo & Juliet" by way of "Eternal Sunshine of the Spotless Mind."
