Finally got round to releasing my film about the discovery and exploration of Sarawak Chamber in Mulu. Dave Checkley, Andy Eavis and Tony White found what is still the worlds biggest cave chamber (by floor area) back in 1980 and I took them back there in 2012 to retell the story of its discovery. Since then been back to Mulu twice to shoot the background material for the story and this is the result.  Available on DVD and HD BluRay discs.
