Creator could add touch of Oz to Frozen 2

The highly anticipated Frozen sequel may have a touch of Australiana in it.

Co-creator Chris Buck has spoken about Frozen 2, about how the top-grossing animated film of all time has changed his life and about the loss of his 23-year-old son in the ABC series One Plus One.

In the interview with Jane Hutcheon to air on Friday, Buck talks about the "overwhelming" pressure he feels to create a sequel for Walt Disney Pictures following the success of Frozen.

"You just have to get past it," he tells Hutcheon.

"We have lots of things to figure out but at least we know where we are going."

Frozen won the Oscar for best animated feature and best Original song for Let It Go in 2014. It took in $US1.27 billion at the global box office and was the second-most pirated title of 2014, racking up almost 30 million illegal downloads.

Buck reveals that the directors have an ending for the Frozen sequel, which is still untitled, and that he may use aspects of his recent visit to Australia to help form the movie's plot line, according to the ABC.

As part of his working holiday to Australia last week, which included sight-seeing, Buck visited the University of Newcastle to speak to students about innovation and creativity.

He speaks of his love for drawing cartoons evolving from the Peanuts cartoon strip and the Disney animation film Pinocchio which was the first movie he saw in a cinema.

In the 1970s, he studied animation at the California Institute of the Arts and his most memorable moment was having his work singled out by Lillian Disney, the widow of Walt.

"I was just floored," he says.

Some of the other Disney productions Buck has worked on include The Fox and the Hound, Pocahontas and The Little Mermaid.
