Lynn Hirschberg: In Shame, which is out now, you play Sissy, a deeply troubled girl with an almost incestuous attachment to her brother (Michael Fassbender), a sex addict. Both characters are in search of something—anything—that will make them feel whole. Sissy, who works as a singer, is naked even when she’s clothed. She reveals too much, sleeps with the wrong men, and when she turns up unexpectedly in her brother’s spare, pristine New York City apartment, the effect is like a bomb going off: The siblings ignite each other’s self-destructive ways. Shame is unsettling and haunting. Is that why you were attracted to the project?
