After its triumph at the 2019 BAFTAs and Golden Globes, Roma’s crowning as Best Film at the Oscars looks all but certain. Worldwide acclaim is a poignant outcome for this deeply personal film, closely modelled on director Alfonso Cuarón’s own childhood in Mexico City. The lead characters, maid Cleo (Yalitza Aparicio) and mother Sofía (Marina de Tavira), are based on his own nanny and mother, and the movie is set where he grew up in the Colonia Roma area of the city, now a very fashionable part of town but then a bourgeois residential area.
