The official international Tintin site has the extensive release dates list, listed by location, for the film, so you can see when it will come to your country!

This is one of those times I wish I lived in England..... they get the film in October, and over here across the pond we have to wait until December! What insanity is that......? Ah well. It will be even awesomer for the wait. Yes, awesomer is a word in my book, thanks very much....
Also, if you're a trailer person AND a Tintin fanatic (though being one or the other will suffice), Empire Online has done a Trailer Breakdown which I found most beneficial. Not that I hadn't already come to the same conclusion for most of the clips, but it was a great read anyway.
Seeing as I speculate and guess at things concerning a film by closely examining it's trailer(s), you could really say that the article is me on steroids.... which, actually, should never happen in reality..... anyway. :P
