Damian Lewis has revealed that he wouldn't be surprised if his Homeland character Nicholas Brody is killed off.
The Emmy-winning British actor, who portrays the US marine, admitted that the show's writing team have to be "bold" and take risks to keep viewers gripped.
"Part of the talent of this writing room is that they're not afraid to kill the sacred cow. They're prepared to be bold in their storytelling," he told Entertainment Weekly.
"Who knows if they've got any more story up their sleeves? But it's been a thrilling ride."
Damian also said the cast and crew are concerned that they will not be able to emulate the success of Homeland's Emmy-winning first series, which also landed Claire Danes, who plays CIA agent Carrie, a gong.
The show has already been picked up for a third season by US network Showtime.
"It's always a little concerning when there's this gush, this flood of success. But it's wonderful and I'm just so grateful that people have really embraced the show and are as enthusiastic as they are. I think we all can't quite believe our luck," the actor said.
"I know the writers were concerned on not being able to top season one. But people have really seemed to enjoy season two and that's even with some of that ambiguity potentially having evaporated in that relationship between Carrie and Brody."
