A great group of emerging film-makers, film and history students took up the World in a Cube Creative Challenge at Birkbeck, University of London. Delighted to welcome Denise Stevens from the USA and Hester Rice  from C3Health to our filming of the Masterclass in Public Health & Social Action for Glagow and Caledonian University at its London campus, in Spitalfields - a lively discussion with a full range of perspectives.
