According to Box Office Mojo the official release date for Steven Spielberg’s The Adventures of Tintin: The Secret of the Unicorn in North America is December 23rd 2011, which also happens to be my birthday. Tintin will be released in countries such as Sweden, Netherlands and Germany in October 2011 as Tintin is rather popular in that part of the world. To date the graphic novel series has sold over 200 million copies worldwide and most of those sales were in Europe, so the studios (Sony/Paramount) have the right strategy even if the US has to wait an extra 2 months for it.
The Adventures of Tintin: The Secret of the Unicorn stars Daniel Craig, Jamie Bell, Andy Serkis, Simon Pegg, Nick Frost and will be using the same performance-capture technology James Cameron used for Avatar, so expect a visual treat.
