Becoming actor by chance in 1987 (he was a jeans salesman in outdoor markets), Roschdy confirms, more than twenty years after his first roles, that French cinema could not have got along without him. Actor for André Téchiné (I Don't Kiss and My Favourite Season) or Xavier Beauvois (The Young Lieutenant), he doesn't hesitate to appear in mainstream comedies with Gad Elmaleh or Alain Chabat. Only restriction for this Frenchman of Moroccan origin: Not to play roles of Arabs setting bombs. In 2006, he comes in Competition to Cannes and leaves with the Award for Best Actor, collectively awarded to the five heroes of Rachid Bouchareb's Days of Glory. In 2006, he switches to the other side of the camera and directs Bad Faith, starring Cécile de France.
