He continued that he particularly identified with the P.T. character, as his journey from a lower class life to the heights of fame mirrors his own transition to becoming an actor - having only bagged his first role aged 26.

He explained: 'This character is made for me. It’s about hope and power of imagination, a true rags to riches story. My dreams as a kid were to be a rock star so this was really great.'

With tracks produced by the same songwriters as La La Land, the actor joked that even his daughter approved of the flick.
