It’s 2001 and nine-year-old Jonno Davies is standing in the crowd as Robbie Williams entertains 65,000 people at the Milton Keynes Bowl.

“He was just this symbol of cool, and that stuck with me for a long time… He was like the rock star of the day for me,” he recalls.

Now 32, Davies is appearing in cinemas around the world in Better Man, a musical biopic in which he plays his childhood hero.

But he is far from recognisable, partly because of his hard work studying and recreating William’s voice and mannerisms, but mostly because he’s represented on screen as a computer-generated chimpanzee.
