Changes from the Book
The Great Dane, Brutus, and Red Rackham's first mate, Diego the Dreadful, are notably absent. Also, when Captain Haddock takes Tintin out of the latter's apartment to show him the painting of the The Unicorn, someone is shown watching them and then breaking into Tintin's apartment, whereas in the book it is only revealed that there was a robbery when Tintin arrives home and finds his model Unicorn missing. This episode depicts this break-in. When Nestor knocks Tintin on the head, Tintin faints, whereas in the book he is simply shown rubbing the spot. Also, near the end, both of the Bird Brothers tell what happened at Marlinspike Hall, wheras in the Book, Max escapes in his Car and only Gustav told the story.
Gustav Bird's role is downplayed and he doesn't seem to talk as much as he does in the book.
