Deadline.com reports that the film doesn't even have a script or a director yet, but Schwarzenegger, who starred in three "Terminator" movies, will be back as a robot from the future.
The 63-year-old had stepped down as governor early this year after serving two terms as the head of the state.
Schwarzenegger is also developing an animated TV show and accompanying comic book series with Spider-Man creator Stan Lee, titled “The Governator".
