If it’s true that your age freezes the day you become famous, then the British pop star Robbie Williams is stuck at 16. So he says near the end of “Better Man," the biopic he produced. “I’m unevolved," he confesses. No kidding — throughout the entire film, Williams is portrayed as an ape.

Robbie Williams being portrayed as a CGI ape in Better Man could have been a simple gimmick, but it actually has thematic meaning within the story.

Nicole ends up leaving Williams (for Liam Gallagher of Oasis), part of a miserable time for the singer, who manages to destroy most of his relationships. But he reaches a career pinnacle, performing at the storied Knebworth Festival to some 375,000 adoring fans.

“In real life I don’t cry that much,” Williams says and then smiles. “You have a (expletive) biography about you and have the world go, ‘I’ve seen you and heard you’ and come tell me how you deal with it.'”

I’m not kidding. And neither are “Better Man” subject Robbie Williams nor the film’s director Michael Gracey. This rise, fall and very fast 12-step recovery saga of the English singing sensation few Americans know presents Williams as a CG chimpanzee.
