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.

But unlike other biopics, Williams and director Michael Gracey came up with a novel twist that has Williams being played by a computer-generated monkey.
