A woman, who claims that director James Cameron and studio executives at 20th Century Fox/Paramount Pictures hijacked her idea to make the April 2012 release "Titanic 3D", has reportedly sued them for $1 billion.

Faan Qin's lawsuit contends that Cameron and his partners copied her idea "R.M.S. Titanic - The Experience", reports tmz.com

Faan said the moviemakers hijacked her idea for a 3D ride that recreates the experience of the cruise that crashed into an iceberg and sank on its maiden voyage in 1912.

Faan claims Cameron's 3D movie has made more than $343 million, but she wants three times that to teach the Hollywood titan a lesson, reports the website.

Cameron's movie on the real life incident released in 1997. Starring Leonardo DiCaprio and Kate Winslet, it was a major success.
