In a Biopic of Robbie Williams, the Star Is a CGI Monkey.

Movies|In a Robbie Williams Biopic, the Star Is a C.G.I. Monkey. Take That.

Dance, monkey, dance. Sing, monkey, sing. The British pop star Robbie Williams has always felt like a performing monkey. He has described himself that way when remembering eras of his life: his days as a young boy, trying to prove to his father that he had the “It factor” required to become a star; when he was a teenager and landed his dream job as the fifth member of the boy band Take That; and finally as an adult trying to start a solo career.

Recent biopics of the band Queen and Elton John have proved that audiences are willing to taking a fantastical ride through pop-stars’ common trajectories of rise and fall and rise again. But will they be so amenable when the protagonist is played by a computer-generated monkey?

Yes, you read that correctly. In the coming musical biopic “Better Man,” the character of Robbie Williams is a chimp, though everyone else around him is human. It’s a leap that the director Michael Gracey, best known for the smash “The Greatest Showman,” is betting moviegoers will take, even those in the United States where Williams is hardly a name despite his international stardom.

The monkey, said Gracey, “was the thing for me that clicked, and it was also the thing that made the film near impossible to finance.”

His plan was to rely on the magicians at Weta FX (“Avatar: The Way of Water”) in New Zealand to design a computer-generated monkey, something similar to the process that turned Andy Serkis into Caesar in the “Planet of the Apes” franchise. For “Better Man,” the stage actor Jonno Davies wore the gray motion-capture suit for the entire production and was then rendered into simian form. For the chimp’s face, the eyes of the actual pop star were used.

This approach not only doubled the budget of the movie, but also seemed just too far afield for most backers. Multiple times, Gracey said, “I would sit down with financiers. They would say, ‘Director of “The Greatest Showman,” Robbie Williams. I couldn’t be more excited about this. How much do you think?’ And I would say, ‘Well, there’s just one thing: Robbie in the film is being portrayed by a monkey.’ And they would say, ‘Oh, yes, in some dream sequence, or he looks at his reflection and he sees himself as a monkey.’ I said, ‘No, no, no, the entire film.’ Their faces would just drop and they would say, ‘OK, well, this is the end of the meeting.’”
