James Cameron sent the cast of his new movie Avatar off to the jungle for bonding bootcamp exercises before he started shooting the upcoming epic.
The Titanic director called on stars including Sigourney Weaver and Zoe Saldana to get a feel for rainforest life, so they could better play their jungle-dwelling characters in the film.
He tells Entertainment Weekly magazine, "We did a sense-memory experiment in Hawaii. We trekked around the rainforest for three days, building campfires and cooking fish, trying to live tribally."
And Saldana insists Cameron's pre-filming jungle expedition was a great idea: "That experience helped us so much.
"Sigourney, Sam and I were shooting the movie on a regular cement floor on a soundstage, but we needed to know what it was like to walk in a jungle world, what that felt like."
Avatar is set to be the must see movie this Christmas and is a return to the director's chair for Cameron after a four year hiatus.
A band of humans are pitted in a battle against a distant planet's indigenous population.
Avatar is released 17th December.
