Dan Slevin reviews three new releases: One Night Only, a comedy set in a United States where pre-marital sex has been legally outlawed by biometric implant, except for one night a year when unmarried adults can let off steam - starring Monica Barbaro and Callum Turner; & Sons, in which Bill Nighy plays a reclusive novelist making one last attempt to reconcile with his two estranged adult sons and have them accept their teenage stepbrother, also starring Imelda Staunton, Johnny Flynn, George Mackay and Noah Jupe; and De Gaulle: Tilting Iron, the first of a two-part epic biography of the French statesman, following his wartime leadership of the resistance in exile, starring Simon Abkarian and Simon Russell Beale.
