Little Devil-May-Care (or The Devil in the Heart) (French: Le Diable au cœur) is a 1928 French-British silent drama film directed by Marcel L'Herbier and starring Betty Balfour, Jaque Catelain and Roger Karl.
L'Herbier had originally made an agreement with the Gaumont-British company to film Labiche's stage farce Un chapeau de paille d'Italie with the popular English actress Betty Balfour.
Soon after filming began several leading members of the cast became ill, including Balfour, and the production had to be halted for a time, incurring greater costs.
Further difficulties were caused by the panchromatic film which was being used for the first time in a French production, and technical inexperience with this filmstock produced a number of unforeseen problems.
L'Herbier subsequently felt that, despite the film's appealing elements and the vivacious humour of Betty Balfour, the finished product lacked rigorous consistency.
