笑容藏于心间，温暖常伴。关于我妈的一切

　　This is another great film by Pedro Costa , a movie about the relationship between a couple of directors ( Danièle Huillet and Jean-Marie Straub) that are trying to edit the film «Sicília!». During that process Straub and Huillet talk about general and particular aspects of the movie industry, in a extremely interesting dialogue.
