Changes from the Book
The part of Philippulus the Prophet is significantly reduced. He is seen at the start of the episode when Tintin reaches the observatory and when Tintin is having a nightmare. These appearances were reduced and others, such as Philippulus' "occupation" of the Aurora's crow's nest, are completely missing. The Aurora's fuel stop in Akureyri, Iceland was likewise left out. Captain Chester is absent in the episode. Also, in the TV episode, the Aurora's crew sees the Peary through binoculars aboard the Aurora, instead of from a seaplane.
