After lengthy negotiations, Dominic West (The Wire, The Hour) has been tapped as the male lead in Showtime‘s drama pilot The Affair. From playwright and writer/producer Sarah Treem and co-creator Hagai Levi, The Affair is an intense and intimate exploration of two marriages and an affair that disrupts them — with all of the complex consequences that result. West will play Noah, a good husband, devoted father of four, and New York City high school teacher whose settled, comfortable world is about to implode when he meets a woman he thinks is his soul mate. Written by Treem, the provocative, one-hour relationship drama will be told separately from the male and female perspective. Treem and Levi executive produce alongside director Mark Mylod.
