Cast lines up for period love-triangle drama. Dominic Cooper (‘The Devil’s Double’) has landed the lead role in low-key drama ‘Summer in February,’ joining Dan Stevens (‘Downton Abbey’), Ophelia Lovibond (‘Mr Popper’s Penguins’) and Hattie Morahan (‘The Bank Job’). Based on the life of celebrated British painter Alfred Munnings and set in an artist’s community among jagged cliffs and crashing waves the story explores the darker side of love. When two great friends fall in love with the same hauntingly beautiful woman, their loyalty to each other is tested to breaking point. Christopher Menaul (‘First Night,’ ‘Prime Suspect’) will direct, helming from a screenplay by Jonathan Smith, who adapted his own novel. The film will begin lensing next month.
