According to the lawsuit obtained by TMZ.com, Qin claims Cameron and his hang copies her idea with something called 'R.M.S Titanic - The Experience' in Orlando, which they've apparently made a killing from.

It's the latest lawsuit concerning the multi Oscar winning movie. In February, an extra who worked on the film filed a lawsuit against 20th Century Fox, claiming he was cast as a non-speaking background actor before being given a speaking part by Cameron. Vi Jay was given the line, "Yes. Yes ma'am" (which he said to Kathy Bates' character as she handed him her luggage).

Jay says he was paid just $60 a day, but claims the line means he's entitled to Screen Actors' Guild benefits, specifically residuals. The movie has grossed over $2 billion since its release.

Back in 2011, James Cameron was sued for more than $2 billion by a science fiction writer who claimed the filmmaker used two of his screenplays for the basis of blockbuster 'Avatar'. Cameron won the case.
