Tintin film

Spielberg has the rights to make a trilogy out of Tintin, First out will be The Secret of the Unicorn and Red Rackham's Treasure. Spielberg won't direct it, he want one European director for this. But the suggested Roman Polanski may not be interested in working with Spielberg, as he wants to have full control of the film and do it in his own style. And Polanski want the more serious King Ottokar's Sceotre to be made, not some Indiana Jones-like adventure.
The most possible thing for Spielberg is to direct himself, and put good friends as George Lucas in the director's chair. But Mr Lucas has made clear that he would never make any bid-budget movie again. So it better be Robert Zemeckis or Irvin Kershner...
What actors do we want to see then? I have four alternatives:
David Boati (1979), Taylor Hanson (1983), Sean Biggerstaff (1983), Bug Hall (1985).
All four are good, but I must only go for one, and that will be David Boati. A Swede, but still the best one of these.
