'Better Man' movie review: Robbie Williams is a chimp. (Just go with it.)

Music biopics are too often predictable, formulaic and, let’s face it, dull. One way to liven them up, however, is to venture way outside the box and make the central subject an anthropomorphic animal. And while an alligator Freddie Mercury in “Bohemian Rhapsody” or a sloth Bob Dylan in “A Complete Unknown” might have been bridges too far, a chimpanzee Robbie Williams defies logic and somehow works in “Better Man.”

Director Michael Gracey’s admirably eccentric biopic/jukebox musical (★★★ out of four; rated R; in select theaters now, nationwide Friday) still boasts the signature tropes of its ilk and the career-tanking vices of many a “Behind the Music” episode. Yet the fact that the ultra-cheeky Williams is inexplicably presented as a bawdy CG ape man (given cool moves and voice via performance capture by Jonno Davies) matches the fantastical nature of the British pop star’s bananas rise-and-fall-and-rise-again tale.

The movie also has a lot in common with Gracey’s most famous effort, “The Greatest Showman,” featuring well-crafted, effervescent musical numbers doing what they can to make up for oversentimentality and an unfocused narrative.

Narrated by Williams himself, “Better Man” chronicles his life starting as a little simian dude playing soccer in the streets with his mates – and failing to impress his peers. Like his father Peter (Steve Pemberton), Robbie wants to be somebody and slowly he begins to embrace a charismatic, wild-child personality that wins him a spot in the boy band Take That. His brazen and outrageous personality wins over some like pop-star girlfriend Nicole Appleton (Raechelle Banno) – and his many fans – but irks many others, from his bandmates and manager (Damon Herriman) to members of Oasis.

The middle of the movie is where “Better Man” finds its groove. Robbie sings “Rock DJ” and his group pogo-sticks through London’s busy Regent Street in the film’s most spectacular sequence. And as the insecure Robbie goes down a bad path, he’s forced to literally fight the conflicting parts of his pop-star persona. Drugs and being a selfish jerk threaten everything, of course, and seeing a chimp go through the out-of-control partying instead of a normal dude is a bit different. The family drama peppered through the film leans too earnest, leading to an ending that pours on the schmaltz way too hard. Brash simian Robbie is a lot more fun to watch than soppy simian Robbie.

No one’s ever going to play a primate like the brilliant Andy Serkis in his “Planet of the Apes” films. Davies does a good job at moving in such a way that's human but also a little bit wild, which adds to the hyperrealism of a proudly oddball movie. It doesn’t completely explain why exactly Williams is a chimp in the biopic – he’s said he feels “less evolved” than others, and Nicole calls Robbie an “animal” during a fight – but it makes that bizarre choice a little less head-scratching.

Interestingly, the best part of “Better Man” is Williams. He sings the songs throughout the movie – including nifty new tune “Forbidden Road” – and his fabulous narration hilariously slings jabs and adds an emotional gravitas to his screen counterpart’s struggles. When the film goes most over the top, Williams’ commentary keeps it grounded.

“Better Man” isn’t perfect – as a straightforward effort, it doesn't hold a candle to, say, "A Complete Unknown." But it’s never boring, either. And the film is easily the most idiosyncratic of its kind, at least until that inevitable Barry Manilow biopic featuring a yeti.
