NDH3's guests were the lovely David Bond and Ashley Jones of Greenlions, the creative team behind the award-winning feature docs Erasing David (2009) and Project Wild Thing (2013).
These guys are experts in audience engagement - creating films and release campaigns that partner with organisations and NGO's who share common goals with the project to reach their audience - they've partnered with Liberty, The National Trust, the NHS, top creative advertising agencies and many more - it's fascinating stuff, and can apply to drama just as as well as doc.
