Peter Jackson says he will direct the follow-up to 'The Adventures of Tintin: The Secret of the Unicorn' when he finishes 'The Hobbit'. The Tintin film currently in theaters is directed by Steven Spielberg. But in The Hollywood Reporter, Peter Jackson answered with a resounding "yes" when asked if he would be responsible for the sequel. There is no green light for the film (yet), but Sony and Paramount have already released a budget to pave the way for it. “The script is already written,” said Steven Spielberg.
