The eastern half now Papua has been at some point English, German, Australian. Walk Into Paradise was made while Australia held a mandate from the Trusteeship Council of the United Nations. Who run's the island is a big concern in Canberra. Spread over the northern shore of the Australian continent like a canopy, New Guinea was the scene of some of the fiercest fighting in World War II. A lot of Australian lives were lost so that the Japanese never mounted an invasion of Australia proper. That being said, for those natives in New Guinea, some of the most primitive people on Earth, they suffered as well because of geography.
I saw this film as a youngster as a second feature of a double bill back in the early 60s. Very few Australian films were shown in the USA then. This one was particularly relevant because the news at the time was filled with the disappearance of Michael Rockefeller, son of Nelson Rockefeller. Americans got to see on the movie screen just what Michael Rockefeller had gotten himself lost in. Made the tragedy all the more real for the general public.
It's one of the most realistic jungle pictures ever done. You can't count the studio Hollywood product before King Solomon's Mines or The African Queen. Americans are terribly ignorant of Africa and most of the rest of the tropical world because of Hollywood.
America also got to see Australia's biggest film star, Chips Rafferty. On the occasions I have seen him, Rafferty never disappoints and definitely not here. He plays a district officer who's sent into the jungle to locate a gold strike.
There are no Hollywood style heroics here. Rafferty plays a man who's just doing a very difficult job under trying conditions of heat, rain, and occasional fever. Gritty and realistic is the word here.
Papua got its independence in 1975 so that world is gone now. But the jungle is there and should be seen in this film.
