MUMBAI: With The Adventures of Tintin: The Secret of the Unicorn doing very well all across the globe, filmmaker Steven Spielberg has already started working on the script for a sequel to the 3-D film.

According to producer Kathleen Kennedy, she and Spielberg are busy with the new script and hope to have the film release by summer 2015 at the latest. "Oh yeah it is being moved forward, in fact Steven and I were talking about it this morning. We‘re working on a script right now, we‘ll see a script probably February or March.

If we can do some camera capture this summer, which I think we could do, then we would be on track to have the movie either Christmas 2014 or summer 2015, and so that‘s what we‘re looking at right now," Kennedy has reportedly said.
