One voices the tooth fairy, the other a teenage boy who brings winter wherever he goes, but Isla Fisher and Chris Pine reckon they can both relate to their character in new animation Rise of the Guardians.

"Tooth always gets stressed when she’s trying to get the teeth ready in time and I feel like that’s similar to me when I’m trying to get my kids ready for the school run,” Isla said at the premiere in London on Wednesday.

To celebrate the movie release a Magical Funland has been built in Leicester Square for everyone to enjoy in the run up to Christmas.

The film tells the story of a group of heroes who have to join forces in order to protect the hopes, beliefs and imagination of children all over the world.

Rise of the Guardians is out in UK cinemas from November 30.
