The actual filming of Steven Spielberg's The Adventures of Tintin: The Secret of the Unicorn has been completed, and it now goes to motion-capture technicians and artists who will spend the next two years finishing it, Peter Jackson, who is producing it, said in London on Tuesday. The film stars Jamie Bell (Billy Elliot) as Tintin. In an interview with the BBC, Jackson said, "Tintin is great. It's made. The movie is cut together and now [we] are turning it into a fully-rendered film. So the movie, to some degree, exists in a very rough state." The film, he revealed, will be released in 3D in late 2011. Jackson, who directed the 2D Lord of the Rings films, indicated that he has mixed feelings about the 3D technology. "The only thing I get annoyed about is the image being a little dull. It does feel like you're looking at the movie with sunglasses on. But literally, that could just be about getting brighter bulbs in the projectors."
