Moana co-star challenges The Rock to People's Eyebrow duel

Dwayne 'The Rock' Johnson has been challenged by his Moana co-star Auli'i Cravalho at his own game - the mighty 'People's Eyebrow'.

The 15-year-old, who voices the title character in Disney's upcoming animated film, doesn't inspire confidence as her monstrous co-star towers over her.

"I can do the People's Eyebrow. I can do it better than he can," Cravalho says in a video on her Twitter account.

But Johnson reckons there's no contest.

"So Auli'i, which I appreciate, she's very confident, but she thinks she can do my thing, my signature thing better than me, which is impossible," boasted Johnson.

The pair then each presented the camera with their best eyebrow efforts - Cravalho pulling a disgusted face after Johnson described his own as "sexy".

Cravalho then reveals a weakness in Johnson's eyebrow game: he can only perform well with his right one.

His left results in a look he likens to his "drunk days".

Moana original music producer Lin-Manuel Miranda announced Cravalho the winner of the eyebrow match, but viewers can make their own minds up.

The film is set for release in New Zealand on Boxing Day.
