The piecemeal process of casting the principals in Showtime’s new series Homeland is now complete.

On Monday, actor Diego Klattenhoff (Mercy, Men in Trees) became the latest confirmed talent to join the series, which has been among the most talked-about pilot projects of any premium cable network in recent months.

According to a report Monday in The Hollywood Reporter, Klattenhoff has been tapped to play Mike Faber, a Marine colonel and the best friend of Scott Brody, who will be played by Damian Lewis, a British actor best known in the U.S. for his work on NBC’s drama Life and HBO’s Emmy-winning World War II mini-series Band of Brothers.

Homeland centers around an American POW who returns after years of incarceration in Iraq. Mandy Patinkin, who has been largely missing in action  in the world of television since leaving Criminal Minds on CBS in 2007, will star in Homeland opposite Claire Danes. Patinkin will play a CIA chief who sends an agent (Danes) to investigate the returning soldier (Lewis) – who is under suspicion for terrorist collusion.

“It’s a great psychological study like all the best Showtime shows,” said David Nevins, the president of entertainment at Showtime who is believed to have closely overseen the conceptual development of the project. “But it actually is much more than that in the fact that it’s a psychological thriller with a real ticking clock and real edge-of-your seat elements.”

Since casting news about Homeland began to leak in the first week of December, Showtime’s drama pilot has generated substantial buzz. Sporting an impressive cast and crew of veteran television actors and producers, Homeland has been described as Showtime’s attempt to launch a 24-like crime thriller. Homeland, after all, is being executive produced by Howard Gordon and Alex Gansa, formerly of Fox’s hit terrorism drama 24. Ironically, Klattenhoff – the latest talent confirmed for Homeland – even had a small part in the 2009 season of 24.

The series – planted firmly in the “terrorism drama” genre – is scheduled to begin shooting next week in Charlotte, North Carolina. If picked up for a full season, expect Homeland to debut on Showtime in  the fall of 2011.
