Pauline Burt, chief executive of the Film Agency for Wales, added: 'As an agency, we are absolutely focussed on supporting Welsh born and/or resident key talent with a particular emphasis on writers, directors and producers. Justin is a considerable talent and we're delighted to have the opportunity to facilitate his next project getting made. His story is original, touching, evocative and has, in our opinion, the potential to travel significantly at an international level.'
