Britton and Bana also are executive producers on the project.
The "Star Trek," "Troy" and "Black Hawk Down" actor will play John Meehan, "a handsome and romantic charmer who sweeps Debra Newell off her feet and pulls her into his web of lies," a news release said.
"The series chronicles the true story of how a romance with Meehan spiraled into secrets, denial and manipulation."
