Maura Tierney near the waterfront in the Dumbo section of Brooklyn, in New York, June 3, 2018. In Showtime’s “The Affair,” Tierney, 53, plays Helen, a wronged wife who, on occasion, appears nude, something Tierney wasn’t expecting in her 50s. “I wasn’t an actress that was cast and celebrated for her sexiness,” Tierney said.
