Reese Witherspoon says her Instagram feed, full of pictures taken on her trip to New Zealand, doesn't do the country's beauty justice."It's the most beautiful country in the world - I've made a lot of movies all over the world, but this is my favourite place I've ever shot," she told radio station The Edge on Friday."You can't capture it in pictures. I would say to anybody who comes to New Zealand, don't just bring your iPhone - you need a major, amazing camera."Witherspoon, who won an Oscar for her role in Johnny Cash biopic Walk the Line, is in New Zealand shooting Disney film A Wrinkle in Time with co-stars Oprah Winfrey, Mindy Kaling (The Office), Chris Pine (Star Trek), Storm Reid (12 Years a Slave) and Zach Galifianakis (The Hangover)."We are making a movie," she told hosts Dom, Jay-Jay and Randell. "I know it looks like I'm just having fun with my girlfriends."In the film, New Zealand stands in for the planet Uriel, a mountainous utopia populated by centaurs."We needed sort of magical locations because it's about going to other universes," said Witherspoon. She promised to come back for a proper holiday."The food is wonderful, the landscapes are gorgeous, but most importantly the people have been so kind and so friendly, and have opened up their homes. We have all been just so touched by what a beautiful experience it has been."Though she wouldn't tell what it's like flying across the seas on Oprah's private jet, she did reveal just where she keeps her Oscar. "I keep it in my living room, and anyone who picks it up has to do a speech."Newshub.
