Kirsty Young's castaway is the writer Frank Cottrell Boyce.

His film credits include Hilary and Jackie, Welcome to Sarajevo and 24 Hour Party People. He's also written TV soaps, radio and stage plays and children's novels.

These days children are his main audience and, as a father of seven himself, he should know what they want. He not only tests his ideas on them, but they keep him focused: 'I need them in the house to make sure I'm not watching telly, or having a four-hour bath - the fact that they're there makes me work.'
