Troll Bridge, from Snowgum Films. Adapted from one of Pterry's short stories with Cohen as its main character. It's on Youtube. You can also see the making of documentary, the whole process is nothing short of miraculous.

It started as an independent production before catching the eye of Rob Wilkins (Pterry's assistant), I believe. And then the financing side was taken over by the estate so that the producers could work full time on the film.
