10 Insanely Expensive Movies You Forgot Even Existed

10. Valerian And The City Of A Thousand Planets

Valerian and the City of a Thousand Planets is the most expensive independent movie ever made, and will probably retain that title for the foreseeable future because nobody on their right mind would spend $200m on a project without the backing of a major studio.

Luc Besson has always done whatever the hell he wants to regardless of whether people think it's a bad idea or not, and the mega-budget sci-fi adaptation ended up causing the stock price of his EuropaCorp company to drop dramatically when it landed in theaters around the world with little more than a dull thud.

Some of the visuals and world-building were on point but Valerian was horribly miscast from top to bottom, and nobody seemed to have much interest in seeing beautiful people giving wooden performances and spouting dialogue from a script that was frequently utter nonsense.

It may have just about scraped the production costs back in theaters, but almost as soon as the credits rolled on Valerian most audiences had already completely forgotten about it.
