HOLLYWOOD—James Cameron, writer and director of blockbuster movies such as “The Terminator” and “Titanic,” hinted that he has decided to add a traditional Bollywood dance sequence to the end of his new sci-fi war film, “Avatar.” “The editors and I have been working on this project for over a decade and we never seemed to get the ending quite right,” said Cameron. “Then it struck us, why not put in a dance sequence!” The world famous director hopes that by bringing all the dead and forgotten characters back to sing and dance in a traditional Bollywood style finale, “Avatar” will receive the added boost it needs to become a serious Oscar contender. Cameron is also currently under negotiations to have Tom Hanks play a mentally handicapped alien who has chance encounters with various important historical figures.
