Cameron Diaz and Seth Rogen on The Green Hornet

Actors Seth Rogen and Cameron Diaz have spoken about the ideas that inspired their film, The Green Hornet.

Rogen, who is also one of the film's writers, said what makes the film unusual is that it is a super hero film in which the hero and his side-kick do not actually like each other.

He said he began writing the plot in 2007, before he starred in the hit comedies Knocked Up and Super Bad.
