'Titanic' writer and director James Cameron wants to work on a less-intense project once he's completed the sci-fi thriller 'Avatar'.

Speaking to The Hollywood Reporter he said: "After 'Avatar', I want to do something a lot smaller."

One film that Cameron is considering is the true story 'The Dive', about the romance between controversial Cuban diver Francisco 'Pipin' Ferreras and his student, Frenchwoman Audrey Mestre.

Mestre went on to become an outstanding diver who broke several world records but died in 2002 while competing.

Cameron said: "It's a drama, a love story. This will require underwater photography, which will look gorgeous in 3-D."
