Downfall is an epic war movie filmed by director Oliver Hirschbiegel, depicting the final days of the Third Reich from within Adolf Hitler's bunker in Berlin.
The film is viewed by many critics as one of the best of the 2000s and was a landmark portrayal of history.
As is the way with web, however, since its release in 2004 a segment where Hitler realises the war is lost and confronts his generals with a verbal volley has been parodied endlessly with a succession of alternative versions with new subtitles added so that the lead character is reacting to some setback to a present-day cultural, political or business reference.
Such versions have included reaction to Usain Bolt breaking the world 100-metre record, launch of the iPad, vuvuzelas at the FIFA World Cup and even one when a string of parodies were removed from YouTube.
So it was only a matter of time before someone - in this case, GuestCentric Technologies - applied it to the business of travel, this time when the Furher learns about hotels going independent with their technology.
