Cynthia Nixon has signed on to guest star in Season 2 of Showtime’s The Affair.

Season 2 of the drama series explores the emotional and psychological effects of an affair that destroyed two marriages, and the crime that brings these individuals back together. This season, the drama will be told separately from four different perspectives, revealing four distinct truths. Nixon will play Marilyn Sanders, a direct and challenging Manhattan couples therapist who is helping Noah (Dominic West) and Alison (Ruth Wilson) come together after a period of strain. Season 2 is currently in production in New York, and will premiere this Sunday, October 4 at 10 PM on Showtime.

The Affair
stars Wilson as Alison, a young woman attempting to move on from tragedy and build a lasting relationship while contending with the judgment of others and her own self-doubt. Her lover Noah (West) is a burgeoning writer trying to balance the temptations of success, the family he left behind, and the woman he loves. Noah’s former wife Helen (Maura Tierney) is attempting to piece her life together while navigating divorce proceedings, care for her children, and her parents’ noxious influence. Joshua Jackson plays Cole, Alison’s former husband struggling to overcome past heartbreak and start a promising new life.
