VENICE: Harry Styles already has an enviable acting resume for a newcomer, from Christopher Nolan's 'Dunkirk' to the upcoming 'Don't Worry Darling' and 'My Policeman.' But the British pop star said on Monday at the Venice International Film Festival that, with acting, he often felt as if he had 'no idea what I'm doing.'

Styles' arrival on the Lido, where 'Don't Worry Darling' is having its world premiere on Monday night, has been one of the most anticipated events of a festival full of stars. At a news conference before the premiere, Styles was peppered with questions about his fans, his career and whether or not he would work with director Olivia Wilde again — neither of which he answered.
