In the documentary 'Le Serment de Tobrouk' presented during Cannes, star philosopher Bernard-Henri Lévy talks about the Libyan revolution and his - reportedly important - role in it. As far as he is concerned, the international community must also tackle Syria. Cynics could also call this film 'How I Led the Libyan Revolution,'" sneers Charlotte Higgins of The Guardian. As far as Hollywood Reporter is concerned, it is commendable that Lévy - 'apart from all the fuss and vanity' - puts his money where his mouth is. "No matter how self-centered his motives may be."
