Oscars 2019: Netflix epic shows there's more to movies than Hollywood  

Alfonso Cuaron's Netflix epic Roma could become the first ever winner of both best picture and best foreign language film at the Oscars.

Its success could change how the category is perceived - and shine a light on the four other worthy nominees, BBC News reports.

In the last decade, there have been changes almost annually to how the Oscars arrive at their shortlist for best foreign language film.

The category has existed since 1947 and the number of films involved grows almost every year. There were 87 this year, and no-one could view them all. So in recent years, volunteers would split into three groups to judge a portion each.
