The construction faire + du Np is an original feature of French syntax. It allows the description of behaviours that corresponds most often to an act of “plagiarising”: when someone fait du Proust, he tries to imitate Proust’s style of writing, and when someone fait du Valls, he reproduces Manuel Valls’ way of governing. The combination of the proper noun of a well-known figure with a partitive determiner evokes not the individual as such, but more broadly the action that their reputation relates to. The use of faire in this configuration is similar that of faire l’aimable, faire le malin. In both cases, it is possible to make use of a possessive determiner : faire son malin, faire son Obama. Hence, which difference in interpretation is there between faire du Obama and faire son Obama? In the first case, we have the political action of Obama in mind and, in the second, rather his way of being, his character. But in certain cases, the difference may be more subtle: as in the case of an actor, is there a semantic difference between faire du Luchini or faire son Luchini ?
