Lily James has some sage advice for anyone who’s struggling to deal with their inner critic. “Talk to yourself like you’re talking to your friend,” she told us from the set of her Harper’s Bazaar cover shoot. “You’re your own worst critic, which is so ridiculous. Why can’t we be kind to ourselves like we are to our friends?”

She continued: “My inner critic is loud and I deal with it by remembering that the voices in your head aren’t fact. I learnt that recently; it was groundbreaking. And it’s so obvious: ‘Oh, the things I tell myself aren’t true, necessarily’.”

James takes on the role of the second Mrs de Winter in a new adaptation of Daphne du Maurier’s Rebecca – alongside Armie Hammer and Kristin Scott Thomas – and it was a role that was perfect for her to play at this particular time in her life, she explains.

“Rebecca’s one of my favourite books, so when the opportunity came around to play the second Mrs de Winter I just couldn’t resist it,” she said. “She’s such an extraordinary character. I was so intrigued by the disparity between how she thinks of herself and how she comes across. I think that’s something that I’ve been exploring in myself so it was this golden moment to play her.”
