For the latest podcast SWH! spoke to documentary filmmaker Darren Hercher about his film Dooman, which airs on BBC Scotland on Tuesday 31st March, 10pm. Shot against the striking backdrop of Inverclyde, Hercher looks at the world of 'doo-flyers' in Greenock, and he explains why he took on the project, the relationships involved, the importance of getting beyond his own - and viewers - initial expectations to uncover the individual stories, explains that time spent filming is never wasted, why each film has to develop its own life and character, suggests that less is often more when it comes to soundtrack, and a whole lot more.
