They say that breaking up is hard to do. But they haven’t met Alex (Romain Duris). He’s the head of a relationship-wrecking crew that, for a hefty fee, will save a good woman from the wrong man. So begins Heartbreaker, a lively and enjoyable French rom-com. Set in the glorious resort of Monte Carlo during summer, the film capitalises on an uncharacteristically spry and wired comic performance from Duris that is just too engaging to be denied.
