Stars to grace Kick-Ass premiere
Aaron Johnson and Chloe Moretz are among the stars due to gather on the red carpet for the UK premiere of zany coming-of-age superhero story Kick-Ass.
The movie, based on Mark Millar's comic book tales, has been helped to the cinema by screenwriter Jane Goldman, wife of Jonathan Ross.
The plot follows a young man who decides to become a superhero, even though he has no special powers.
The film has already attracted controversy, with some arguing it blurs the lines between adult and child entertainment.
The premiere takes place in London's Leicester Square.
