Following in this spirit of non-naturalism, Potter's characters are frequently "doubled up"; either by using the same actor to play two different roles (Kika Markham as both the actress and the escort in "Double Dare"; Norman Rossington as Lorenzo the gaoler and the English traveller in "Casanova") or two different actors whose characters' destinies and personalities appear interlinked (Bob Hoskins and Kenneth Colley as Arthur and the accordion man in "Pennies from Heaven"; Rufus (Christian Rodska) and Gina the bear in "A Beast With Two Backs").
