Actor and director Gael Garcia Bernal talks about his journey from stage school to working with some of the biggest names in Latin American cinema, why it is impossible to take the politics out of Mexican filmmaking and the 'cage of melancholy' that surrounds his country's cinematic tradition. "I understood the nature of cinema. When it's good, cinema can be one of the most important things in a person's life. A film can be a catalyst for change. You witness this and it is an incredibly spiritual experience that I'd never lived before; well, maybe only in a football match." Geoff Andrew speaks with Bernal at an audience Q&A.
