"When Loach selects his actors, whether professional or not, there are certain givens. He will not cast against class: "You carry your class with you in how you talk, how you behave, how you pick up a fork. You can't really act it, and you can't act a dialect." But he stresses that while a professional's training can be a handicap, equally there are parts usually when they are precisely scripted and information has to be revealed in a certain way that could not be handled by non-actors. Loach has used many good non-professionals, but Crissy Rock is phenomenal. He says he auditioned 300 people for the part, two-thirds professionals, but she was the best. Watching the film, you have to believe him."
