The character I’m playing is called Joe and he’s a young GP who when we see him is quite depressed really, but he’s totally in love with Alison. He’s not got that much confidence and he’s in a war zone being attacked by worm-like aliens so things aren’t going well for him.

He’s trying to keep it together for him and his baby Alison who he absolutely adores. I think he knows he’s fighting a losing battle. You know that thing where you know you love someone but you’ve got to set them free, it’s that kind of thing.
