Nothing new, but this from an article in the India Tribune:
Tintin’s global reach can be best gauged from the fact that Hollywood has had its eyes on Herge’s hero for several decades. Indeed, Tintin has also been the subject of several full-fledged motion pictures around the world. But none would have been bigger than the one that is currently in the works.Steven Spielberg, no less, owns the rights to a trilogy of live-action Tintin films. Plans have been on the drawing board since the early 1980s. But according to reports from Hollywood, Spielberg has now confirmed that the Tintin trilogy, dormant for long, is indeed moving ahead. When the films do get off the ground, they will reportedly be a joint venture between Spielberg’s DreamWorks and Universal Studios.
Speculation is already rife about the Tintin stories that Spielberg will take up for screen adaptation. Although Destination Moon and Explorers on the Moon is believed to be one of the pairs of books in the running, the other adventures that run over two separate books – The Secret of the Unicorn and Red Rackham’s Treasure; The Seven Crystal Balls and Prisoners of the Sun; and The Blue Lotus and Tintin in Tibet – stand the best chance of being successfully adapted.
