In every good story there’re always the goodies and the baddies. James Millar is currently playing the evil tortuous villain that is Trunchbull, the school mistress in Matilda. She’s a former Olympic hammer thrower, a cruel and sadistic disciplinarian who throws children around by their pigtails, makes them eat entire cakes on stage and forces them into the hold. And it’s a role James Millar is loving.
