10 Insane Things You Won’t Believe Movies Spent Money On

10. A Replica London Eye - A Knight's Tale ($500,000)

A Knight's Tale is one of those films that both defies genre and is impossible not to love. With its colourful cast, strange but endearing story, it's clear to see why it is now such a cult favourite.

Part-way through the film, when the unlikely group of protagonists head to the jousting championship in London, audiences are treated to an aerial view of the city.

The shot comes complete with a bizarre, easy-to-miss reconstruction of the modern London Eye, made to look both similar to the real Eye and in-keeping with the medieval aesthetic of the movie.

Apparently, the replica Eye was made out of wood and thrown in by the filmmakers as a kind of joke - a joke that cost the movie half a million dollars.

Given how hard it is to see the overpriced prop and how much it set the movie's budget back, it's fair to say the joke didn't really work and it was not money well spent.
