Changes from the Book
In the mental hospital, the cell is a padded cell, while in the book it has a bed. Dr. Finney is a member of the gang so he wrote the letter saying that Tintin was mad. In the book, the fakir copied the doctor's handwriting and wrote the letter. In the comic an unnamed Japanese man is a member of the gang. In the TV series, the unnamed Japanese is replaced by Allan Thompson, whom Tintin recognizes.
Following the chronology of the books, Tintin does not see Allan until The Crab with the Golden Claws, but as the TV series episodes of The Crab with the Golden Claws, which aired before Cigars of the Pharaoh, Tintin's recognition of Thompson is credible when the episodes are viewed in that order. Furthermore, there could exist the possibility that in the series Tintin had briefly seen Allan when he was inside the sarcophagus, on Allan's ship, though in the book he's unconscious the whole time. In the TV episode when Thompson and Thomson come into Tintin's cabin, Tintin already knows them, while in the book he does not. Tintin is not recaptured by the asylum; instead he is found by the Maharaja of Gaipajama's son.
