Dust Bunny

“Dust Bunny” is set in a half-storybook, half-nightmare vision of New York. Its main character is a little girl named Aurora (Sophie Sloan) who’s convinced there’s a monster under her bed, but can’t get her parents to take her seriously. At the same time that she’s failing to convince her parents that their lives are in danger, Aurora begins spying on Mikkelsen’s character, who lives across the hall in Aurora’s apartment building, and slips out late at night with furtive expressions and a keen awareness of who’s watching him. He is never given a formal name. He calls himself Resident 5B, after his apartment number, or 5B for short, while the closing credits list him as “Intriguing Neighbor.”
