Rumour has it Peter Jackson will do a Tintin movie (with motion-capture, which could be very good or very bad, but I'm willing to give Jackson a chance here). Also, Youtube has clips (in Dutch), of a recent Tintin stage musical (pretty good, although their Tintin sort of looks like Scott Thompson, and Snowy is beige), and here's a picture of the Incan mummy Rascar Capac was based upon.
