Dwayne Johnson's wrestling fans have teased him for playing a tooth fairy.

The grappler-turned-actor - who stars in new fantasy film 'The Tooth Fairy', in which he dons a giant pair of wings to collect the incisors of small children - has revealed not everyone has been supportive of the comic role.

Dwayne - also known as 'The Rock' - said: "There are definitely people who disagree with certain creative decisions you make... pleasing everyone is pretty hard."

Despite this, the 37-year-old actor is prepared to take on lots of different roles because nothing "fazes" him.

He said: "Because of my wrestling background, nothing a director can throw at me on a set can faze me. I learned a long time ago how to be coachable... I'm trying to be very smart and focused with my decisions, but it isn't like I sat down and thought, 'OK, now I want to go and take over the family market.' "
