Ray Richmond contributes to Deadline’s TCA coverage.

Following Showtime‘s executive session today at TCA, the network’s entertainment president David Nevins was asked about potential cast turnovers on Homeland. “Anything is possible in television, so I would not rule it out,” he said. Deadline later asked Nevins if there is potentially a scenario in which stars Claire Danes and Damian Lewis leave Homeland early. “Absolutely,” he said. “Do I think it’s conceivable that the show outlives Carrie Mathison and Nicholas Brody? Absolutely… There you go.” Is such a departure imminent? “No, and I mean no spoiler by that. I would not conclude there is a blockbuster in Season 3. But if you’re going to commit yourself to being unpredictable and going where the story takes you, you’ve got to commit yourself to being unpredictable and going where the story takes you.” So nobody on Homeland is safe or sacred? “Exactly.”
