'Titanic' director James Cameron's next film, the sci-fi thriller 'Battle Angel', is moving ahead.

The Hollywood Reporter says that while movie studio 20th Century Fox would not confirm that the film had been greenlighted, the search for the lead actress has begun.

The casting ad seeks female applicants from 16 to mid-20s with athletic ability and an ear for languages.

Since 'Titanic' was released Cameron has directed a number of underwater documentaries.
