First World War drama 1917 was the big winner at the BAFTAs on Sunday, picking up seven awards including best picture and director for Sam Mendes, the first time he has been honoured for direction by the British academy.

The thrilling drama, shot in what appears to be a single take, was also honoured in the outstanding British film, sound, production design, cinematography and special visual effects categories.

Britain's top movie awards have been criticised for having all-white shortlists in its acting categories and an all-male one for director, triggering the use of the hashtag #BaftasSoWhite on social media.
