"Douglas is a bit of a bookworm", says Abbi who is Brian Davey's daughter in real life. "He's well brought up by 'no-nonsense' parents, and a lover of fantasy. A realistic child, advanced for his years but still a child inside - a bit like me really!"

But what about playing an American? "Very challenging and interesting to play - it's good to have to sustain a believable American accent."
