Viaggio ai confini della terra

This film gives the impression that Amundsen's rival, the British explorer Robert Falcon Scott, used only ponies and motorized sleds, whereas in fact he started his attempt to reach the South Pole with more dogs than ponies on his unfortunate trip but he did not use dogs on the last leg of his trip contrary to all advice and counsel.

'I can't sleep. I guess I'm still on Canada Time' says a character who has just arrived in Norway from Canada, alluding to jet lag. However, the film is set in 1923 and the only way to have made that journey would have been by sea and rail in around 12-14 days. More than enough time to have adjusted to any time differential.
