Still, Rick himself is above such abuse. “I don’t buy or sell human beings,” he informs Ferrari (Sydney Greenstreet), the city’s black-market kingpin. But as time goes by, Rick realises that turning a blind eye to the buying and selling is just as bad. There is a touching scene in which he rigs the café’s roulette wheel so that a Bulgarian newlywed (Joy Page) doesn’t have to sleep with Renault – thus bringing a tear to the eyes of Rick’s employees and to the audience alike. More moving still is the scene in which the café’s head waiter (SZ Sakall) has a brandy with two elderly Austrians who are about to leave for the US, and compliments them on their broken English. Rainer Werner Fassbinder, the German director, declared that this humane little sequence boasts “one of the most beautiful pieces of dialogue in the history of film”.
