SCANDINAVIA: One Direction stars were living in the wild during filming for their new 3D movie. The boyband heart throbs spent a night sleeping rough and ''foraging'' for food in scenes recorded for 'This Is Us' in what has been described as an ''extreme survival-type feature''. A source told the Daily Mirror: ''This was one of the last scenes left to be filmed for the boys' movie so they really gave it their all. It's a back-to-basics, extreme survival-type feature and the lads were all up for roughing it overnight.”–ES
