Steven Spielberg has confirmed that he is likely to co-direct one of the Tin Tin movies with Peter Jackson. There will be three in the series and one of them could see the two teaming up.

Steven Spielberg was talking about how he saw the three Tin Tin movies being made:

We are going to make three Tintin movies back-to-back. I'll direct the first one, Peter will direct the second one. We'll probably co-direct the third one.

The quote comes from stuff through /film. So not one, not two but three Tin Tin films. The first film should start filming this autumn. Seems strange that they would co direct, I wonder what that's going to look like...
