On the making of GLASS: a portrait of Philip in twelve parts: All in all, making this film has been a return to my roots as a filmmaker - pursuing an idea of personal passion, living it by the skin of your teeth, figuring out the financing and maintaining the persistence of vision you need to realise the dream.  I've enjoyed returning to the documentary form of story telling after more than a decade away from it - with all its unexpected developments, frustrations and delights.
