David Harewood has revealed he has to keep the plot details of Homeland a secret, even from his mum.
The British actor, who plays David Estes in the hit show, said that despite his mother's curiosity, he keeps the scripts close to his chest.
"After every episode of the first series my mum rang me and went, 'Ooohhhh.. what's going on?' I had to say, 'Mum, I'm not saying anything'," he admitted.
Some fans of the award-winning show have expressed doubt that it will be able to deliver a second season that can rival the first.

But David insisted: "These writers are fantastic. They've managed not only to recreate the same amount of tension, but to ratchet it up again. I think fans of the show are going to be very, very pleased."
David also added that his character is being made more prominent in the second series, instead of simply being "the authority figure in the background". He said he was pleased that the writers agreed to give him "much more of a personality".
David, who was trying to crack a US series for "so long" said Homeland "isn't just another detective show, this is a whole other level up".
