Former ER actress Maura Tierney is to star opposite The Wire's Dominic West in the pilot episode of The Affair, a planned new drama from US cable network Showtime.
TVLine.com reports that The Affair has been described as "an intense and intimate exploration of two marriages and an affair that disrupts them".
Tierney will play Helen, the wife of West's cheating character Noah, with Luther and The Lone Ranger star Ruth Wilson playing the "other woman", Alison.
The series, written by In Treatment's Sarah Treem and Hagai Levi, will tell the story from both the male and female perspectives.
