One of the few documentaries shot in the wide screen 2.35:1 format.
This film, according to a review by Ian Jane posted on 10th August 2007 at the 'DVD Talk' website, was ''one of the first documentary films to concentrate on sharks, the Great White in particular, and it was reportedly a big influence on [Steven] Spielberg's 'Jaws'.''
The expedition commenced in March 1969 in Ceylon, South Africa, Mozambique according to an article in 'Filmfacts' (1971). The expeditioners had failed to locate a great white shark by August 1969, and as such, leader Peter Gimbel suspended the voyage until January 1970. It is then when they traveled to Dangerous Reef off the coast of South Australia where great white sharks had recently found to be in wide existence.
The Latin name for the great white shark, as stated in this documentary, is ''Carcharodon carchar''.
A number of the underwater scenes in this documentary were filmed using shark-proof cages which were the anti-shark diving cage / elevator equipment developed by Peter Gimbel.
