10 Greatest Movies Never Made

2. The Man Who Killed Don Quixote

If Terry Gilliam cannot adapt a story then it is fair to say it is unfilmable. Zack Snyder directed Watchmen after Gilliam failed but his movie is so bad it would have been better if it never existed.

Unlike most of the films on this list, Gilliam actually started filming Don Quixote and it was to be his most ambitious project yet, which is saying something after the likes of Brazil and Twelve Monkeys. It wasn't the first time somebody had tried and failed to make the movie either, as Orson Welles notoriously tried and failed many years earlier.

Gilliam spent over a decade developing and working on the project and all that was left to show for it was a shoot that collapsed in five days, a severely ill star, and an intriguing documentary about the failure to make the picture. The insurers shut the shoot down after a multitude of problems that involved shooting next to a military base and massive floods that wiped out the gigantic sets. Gilliam is the great maverick director of his time and I can't help but feel we missed out on a masterpiece.
