After playing Mark "McSteamy" Sloan for six seasons on ABC's Grey's Anatomy, Eric Dane sets sail as Commander Tom Chandler in the new TNT drama series The Last Ship. The series is set on a U.S. naval destroyer, whose crew members under Tom Chandler's command are among the last living human survivors after a global pandemic. I recently had the chance to speak with Eric Dane via satellite, where he discussed preparing for this role, observing the crew members of the U.S.S. Halsey, how TNT has been creatively supportive of the show, while offering insight into future episodes, including one where they travel to Guantanamo Bay and run into trouble with al-Quaeda. Take a look at our exclusive interview with Eric Dane for TNT's The Last Ship before next week's episode, "Dead Reckoning" debuts Sunday, July 6 at 9 PM ET only on TNT.
