Fringe and Dawson’s Creek alum Joshua Jackson is making the jump to Showtime for the cable channel’s pilot The Affair. Jackson will play a Long Island cowboy (that’s not a metaphor, his character actually manages a ranch) in the drama that deals with spouses, wandering eyes, and the effects of an affair on two families.

The Wire’s Dominic West was previously announced as a cast member. He’ll play Noah, a high school teacher with four kids who begins an affair with Cole’s (Jackson) wife Allison (Luther’s Ruth Wilson.) Maura Tierney (The Good Wife) also stars in the pilot as Helen, Noah’s college sweetheart and wife of 17 years.

House of Cards producer and writer Sarah Treem is heading up the project with her In Treatment colleague Hagai Levi and Mark Mylod (Shameless). The press release announcing the news notes “this provocative, one-hour relationship drama will be told separately from the male and female perspective.”
