I've just been looking at this year's program for the World Community Film Festival, and it's looking like again this year there will be some inspiring food related films.  I find it very hopeful that the focus on food issues by the film industry seems to be shifting towards positive actions and community-based approaches to food security, and less at scary agribusiness and GMO documentaries.  
In particular, the film 'Good Food' looks interesting!  Check out the full festival program here.
