Director of CPS George Castle

Bill Paterson plays London Crown Prosecutor Service Director George Castle in seasons 1-2. As boss to James Steel and Alesha Phillips, he runs a tight ship; he keeps the pressure on, but highly esteems and is quite protective of his two younger associates. A man driven by rationality and a sense of justice, “he wants to see bad people prosecuted and he is not prepared to be too liberal about things,” says Paterson.
