Robbie Williams' unique biopic Better Man has landed a strong Rotten Tomatoes rating ahead of its UK release. The film sees Robbie portrayed by a CGI chimpanzee (performed by Jonno Davies) with the singer himself providing the narration.

Let chimpanzee entertain you in a wonderfully bizarre — but still formulaic — musical from the director of "The Greatest Showman."

I’ve seen all the musical biopics, from this year’s A Complete Unknown and Back to Black (bad, but not as bad as some say) to old-school selections like The Buddy Holly Story, Bird, St. Louis Blues, and loads of others.

It sounds like a bad joke. Robbie Williams, one of the best-selling music artists on the planet, portrayed as an all-singing, all-dancing chimpanzee in his very own rock biopic? Pull the other one, mate.

Starring Robbie Williams, Jonno Davies, Steve Pemberton, Damon Herriman, Raechelle Banno and Alison Steadman. Written by Simon Gleeson, Oliver Cole and Michael Gracey. Directed by Michael Gracey. Opens Wednesday at Cineplex Scotiabank Toronto.
