Joshua Jackson, known for his roles on the cult-favorites "Dawson's Creek" and "Fringe" has been cast in the new Showtime pilot "The Affair."

The role marks Jackson's first non-network television role and first major TV role on a premium cable channel, which sometimes features sexually-explicit content. Jackson spent six seasons as Pacey Witter on the WB's "Dawson's Creek," alongside James Van Der Beek and Katie Holmes, and most recently spent five seasons as Peter Bishop on FOX's "Fringe."

Jackson will take on the role of Cole, a hard-edged cowboy who manages a ranch that has been a part of his family for generations on the eastern end of Long Island, New York. Cole's wife Allison, played by Golden Golbe nominee Ruth Wilson, works in a pancake house as she attempts to put her life back together following a tragedy.

Cole and Allison's marriage becomes contentious when Allison begins an affair with Noah, played by Golden Globe nominee Dominic West, a New Yorker who spends the summer with his family on Long Island. Emmy nominee Maura Tierney rounds out the cast as Noah's wife Helen, whose world is shattered by Noah's infidelity and swings back and forth from understanding to vengeful.

"The Affair" comes from the mind of award-winning playwright Sarah Treem, whose works includes the Netflix series "House of Cards" and the HBO drama "In Treatment." Treem and writing partner Hagai Levi, who wrote the original script with Treem, serve as executive producers alongside director and executive producer Mark Mylod, whose work includes the Showtime series "Shameless."
