Hollywood stars turned directors Jodie Foster and Sean Penn will show their latest films at the Cannes film festival next month, the organisers said Thursday.

Director Steven Spielberg will also unveil his take on Roald Dahl's classic children's book "The BFG" (Big Friendly Giant) at the French festival, the biggest and most important in the movie calendar.

Foster's Wall Street thriller "Money Monster" stars George Clooney while Penn's former girlfriend Charlize Theron is the lead in his love story set among aid workers in Africa, "The Last Face".
