Synopsis
25 years ago, on the set of the film ‘Land and Freedom’ by British director Ken Loach, everyone gave so much of themselves that they lived it rather than acted. We delve into the hearts of its protagonists and recall an experience that marked them vitally and professionally. In the background, the eloquent landscape of the Maestrazgo and the Civil War.
