Football legend Éric Cantona is back on the Croisette with two films in Cannes: "Marvellous Mornings", the debut feature from director Avril Besson, and "Cantona", a British documentary exploring his turbulent years at Manchester United. Away from the premieres, the festival is also facing a growing political controversy after hundreds of film figures accused Canal+ and billionaire Vincent Bolloré of contributing to a far-right shift in French culture.
