Dickon Hinchliffe (Winter’s Bone, Leave No Trace, Out of the Furnace, Locke, Peaky Blinders) has recently scored the upcoming Netflix documentary Into the Deep. The film is directed by Emma Sullivan who started documenting amateur inventor Peter Madsen in 2016. A year later, Madsen brutally murdered Swedish journalist Kim Wall on his homemade submarine in the waterways outside Copenhagen. Mette Heide (Amanda Knox) and Roslyn Walker are producing the project.
