How do Steven Spielberg and Peter Jackson, the two titans of pop culture, collaborate on the new 3-D motion-capture version of Tintin? With lots of high-tech wizardry. Spielberg, who’s directing the first instalment, The Adventures of Tintin: The Secret of the Unicorn, recently wrapped 32 days of performance-capture shooting in Los Angeles. Producer Jackson travelled from his New Zealand home base to Los Angeles for rehearsals and the first week of shooting, and then appeared via an elaborate video-conferencing set-up for the rest of the shoot, using a specially designed iChat-type system in which the Kiwi filmmaker can see everything on the set in real time and simultaneously talk with Spielberg. The film is scheduled to hit theatres in 2011. More lines to learn
