If the first Tintin movie is a success then you can be sure that The Adventures of Tintin: Red Rackham's Treasure will be fast-tracked for production. Based upon the 12th Tintin, the second movie will follow Tintin and Captain Haddock as they attempt to scour the sea for the treasure once carried by the pirate ship known as the Unicorn. Steven Spielberg will likely sign on to direct the second film in light of his work on the first.
