That was over a year ago, but new behind the scenes footage shows the former Harry Potter star filming scenes in Mt Tamborine, which easily passes for the Amazon jungle where the movie is set.
It tells the true story of Byron Bay resident Yossi Ghinsberg who became trapped in the Bolivian rainforest for three weeks in 1981. Mr Ghinsberg said he was “instantly happy” with the casting of Radcliffe.
“Daniel had a lot of passion for the story. He spent some time with me and we got to know each other before filming,” he said. “I think he’s done an amazing job with the interpretation, it was a lot of hard work for him in terms of losing weight.
“He was hungry and went through a lot of hardship … nobody thinks of him as Harry Potter anymore. “We spent three weeks on set on the Gold Coast but I was a bit worried because the Amazon is very mighty but this forest (Mt Tamborine) was a bit tamer. “The cinema is all about illusion though and it looks great on screen, you can’t tell the difference.”
