You've got to love anyone who has the same worldview of zombies as he does of living humans. He should return the favour and ask Moz to cameo on the Walking Dead as someone idling the hours in the local graveyard as the graves erupt. "Anyone who says they want to eat my flesh shall be spanked by me with a wet plimsoll!".
Aside: David's acting in the 'Red Riding' trilogy was superb. 'We're from the north. We do what we want.'
