Director Steven Spielberg and producer Peter Jackson present The Adventures of Tintin: The Secret of the Unicorn in eye-popping 3D and on the edge of uncanny valley. The duo is taking advantage of Jackson’s Weta Digital company for the Polar Express-esque visual effects. Edgar Wright (Scott Pilgrim vs. the World) is a credited writer, and the cast of voices include Jamie Bell, Andy Serkis, Daniel Craig, Simon Pegg, and Nick Frost. The trailer is certainly adventurous but until I see the animated characters speak it’s hard to grade the level of pure realism instilled here. The Secret of the Unicorn, the first of three proposed movies to make a Tintin franchise, hits theatres December 23, 2011.
