One of his Kong stars, Jack Black, recently said that Jackson only wanted "to do things that were interesting to him as a kid", and indeed he has many childlike qualities, including a disdain for all things sartorial. That said, Jackson, 44, has shed a good deal of weight since his last public appearances 18 months ago, the result of a health regime he undertook at the end his last project, the Lord of the Rings trilogy. His diet was simple: he cut out all junk food and ate only fruit and vegetables.
