HISTORIAS EN KILÓMETROS (Stories in Kilometers—HEK) is a community film laboratory with a social impact. Its mission is to train, produce, and disseminate films through work with diverse communities in the national and international territories. HEK's objective is to articulate cinema with the life and context of each local team to generate original audiovisual content created by responsible and sustainable production teams. HEK has four laboratory areas. The HEK training lab includes four on-site workshops and a year of weekly virtual sessions, free of charge. This process generates the knowledge to build sustainable, independent, socially responsible film production companies. The HEK production lab partners with training lab graduates to create new projects and explore innovative models for community cinema that engage mass audiences and foster community participation. The HEK diffusion lab's objective is for the communities to be the first audience of all audiovisual creations. HEK has taken giant screens to more than 15 communities worldwide to premiere audiovisual works. The HEK investigation lab researches the context in which HEK works, tailoring its methodology to the reality of each local team.
