10 Cancelled Horror Movies We'll Never Get To See

10. World War Z 2

World War Z had such a chaotic production, there were times when it looked like it would never be released. Not only was the undead thriller repeatedly delayed, the entire third act had to be reshot, ballooning the budget to $269 million and making it the most expensive horror movie ever. Because of this, not even Brad Pitt's star power seemed like it could salvage this mess.

Against the odds, WWZ earned over half a billion and was the most financially successful movie of Pitt's career. Following the zombie extravaganza's success, a sequel was greenlit by Paramount Pictures, with David Fincher chosen to direct.

The follow-up reportedly had a more grounded and global approach to the zombie outbreak, exploring more political and military elements from Max Brook's novel that were left out of the first film. However, things fell apart when Fincher left to focus on his TV drama, Mindhunter. 

Although China is a major market for Hollywood, they have a strict ban on depicting zombies in movies, minimising the chances of WWZ2 turning a profit - the first instalment wasn't released in China either - and with Paramount focusing on financially viable products like Mission: Impossible and A Quiet Place at the time, it wasn't a surprise when World War Z 2 got the chop.
