The hero of the 2018 Thai cave rescue, Dr. Richard “Harry” Harris, attempts the world’s deepest dive in Jennifer Peedom’s (Sherpa, SFF 2015 and Mountain, SFF 2017) enthralling documentary.

This special screening will also include a spoken introduction with Jenny Neighbour and a live Q&A with producer Blayke Hoffman and Richard Harris moderated by Jenny Neighbour.

You know the dangers, but you simply must do it anyway, not because of the danger, but despite the danger.  Deeper captures that feeling, that emotion, that drive, perfectly. 

Peter Martin, ScreenAnarchy

Into the world’s deepest cave — and the depths of human ambition

In a remote part of New Zealand’s South Island, "Harry” and his fellow underwater obsessives set out to dive deeper than anyone ever has before. Controversially, they plan to use hydrogen as a breathing gas – its explosive nature adding to the many hazards the close-knit team faces. As the 2019 Australian of the Year prepares to confront the dark waters and life-threatening cold, he questions the costs of his passion. In this SXSW-selected nailbiter, Peedom and co-director Alex Barry capture the tension, euphoria and mateship of this endeavour using Harris’s own vertigo-inducing cave footage, along with DOP Ben Dowie’s striking above-ground imagery and a compelling score by multi-award-winner Antony Partos.
