I went in not expecting much, and not in the best mood, but this wartime story about love, courage, sacrifice, heartbreak and film-making won me over very quickly, turning out to be an unassuming, unexpected delight. The writing is warm, thoughtful and witty and the cast is tremendous – Bill Nighy is an irrepressible joy; Helen McCrory, Sam Claflin, and Eddie Marsan are all great and I was so pleased to see Jeremy Irons, I almost clapped my hands. The heart of the film, though, is the wonderful, luminous Gemma Arterton, who not only holds her own against a raft of top-tier talent, but is never less than mesmerising. All of which means that “Their Finest” is a genuinely lovely, funny, deeply moving film with humour, sorrow and humanity in abundance. I loved it.
