Los Angeles — Alfonso Cuaron was named best director by his peers on Saturday for his semi-autobiographical film "Roma," cementing his front-runner status ahead of the Oscars in three weeks time. In one of the last major Hollywood ceremonies before the Feb. 24 Oscars, the Directors Guild of America (DGA) awarded its top prize to the Mexican director for his critically-acclaimed black and white movie about a domestic worker in 1970s Mexico. — Reuters
