Brad Bird has begun work on 'The Incredibles 2'.
The 57-year-old screenplay writer has revealed that he's started penning the sequel to the hit 2004 Disney and Pixar film, which won the Oscar for Best Animated Feature, but also says that smartphones and tablets make it difficult to keep elements of the movie under wraps.
Speaking to NPR, Brad said: "I'm just starting to write ['The Incredibles 2'], so we'll see what happens. It's very difficult nowadays because everyone has a device with which they can ruin your movie. They print things on red paper so that nobody can copy them, but they also make them impossible to read when you're on the set."
The original film was one of Pixar's most successful productions, having grossed more than £408 million.
It tells the story of a family of superheroes forced to hide their powers and live a quiet life until they are drawn into the limelight when a villain puts the world at risk.
Samuel L Jackson voiced Frozone in the first film, and last year hinted that his character will probably be returning.
The 'Pulp Fiction' actor said: "Every time I run into Brad he always tells me Frozone is part of what's going on, so I have to believe that.
"I guess they could be 'The Incredibles' without Frozone, but I think Frozone would be a wonderful addition to what's already there. I'm just looking forward to seeing what Jack-Jack turned into."
