Roma, a Spanish-language black-and-white Netflix film, has been named the best film of the year in a string of US critics' awards, confirming its place as one of the leading Oscar contenders.
The family drama, set in Mexico in the 1970s, was written and directed by Alfonso Cuarón, who also made Gravity.
It has been named the best film of 2018 by critics' groups in Los Angeles, New York, Chicago and San Francisco.
Bookies still make A Star is Born the favourite for the best picture Oscar.
But Roma is not far behind in the betting odds and in the rankings compiled by award prediction site Gold Derby.
The film revolves around two women – a housekeeper played by Yalitza Aparicio, who wasn't a professional actress but has won wide acclaim; and her employer, a middle-class mother played by Marina de Tavira.
Inspired by Cuarón's own childhood, it has collected a galaxy of five-star reviews, being described as "an epic of tearjerking magnificence" by The Guardian and "a heartfelt masterpiece of mood and nostalgia" by The Wrap.
