The copy I received,titled 'Thai NTSC import',has English and Thai soundtracks and Thai sub titles which can be switched off when viewing with the English soundtrack.The brand name on the publicity is 'Triple X Film'.
There are NO ENGLISH SUB TITLES on this dvd contrary to the details in the technical description of the 'Thai NTSC import' version.
It is correctly described as an 'All Regions' disc.
The film itself is magnificent and perhaps made before its time which is probably why the film has received little recognition in nearly 50 years.
Dialogue and plot are minimal which is why it stands up so well today:no lavish props or cgi's.
Cornel Wilde's other epic Beach Red [DVD] [Region 1] [US Import] [NTSC
] has elements of the beach landing directly copied by Steven Spielberg in the brilliant Saving Private Ryan 60th Anniversary [DVD] [1998
There is no need to remake 'Prey' as it's so complete and utterly absorbing.
Be warned:the opening scenes are very disturbing.Which is why I remember the film so well having seen it at the cinema in the late 60's.
