We've been heavily covering every little dribble of news on the sequel to 2011's The Adventures of Tintin: The Secret of the Unicorn, growing bit-by-bit more excited with every titbit. So far, we know the film will introduce Professor Calculus, but that it's likely not based on The Calculus Affair (we also heard that the third film will apparently adapt Prisoners of the Sun). We also heard in December that director Peter Jackson intends to shoot the film's motion-capture during post-production of The Hobbit: Desolation of Smaug later this year.
