Firth and Diaz attend Gambit premiere in London

Cameron Diaz and Colin Firth hit the red carpet together for the London premiere of their new film, Gambit, on Wednesday.

The pair star in the Cohen Brothers comedy about an art curator who seeks revenge on his boss.

Speaking on the red carpet, the film's director, Michael Hoffman, said it was an "honour" but a "huge challenge" to direct.

Oscar-winning Firth told reporters that he would be terrified to attempt the same kind of farce on stage.
