12) Justice League (2017) – $300M

The re-shooting, the exiting director, and the extensive CGI made Justice League a very expensive film. Once Zack Snyder had left the shooting floor, Joss Whedon went there and made new shooting and changed all the colors of the film. The re-shoots and CGI fight scenes made the budget blowout quite extreme. Despite its later run, Zach Snyder's Justice League remains a popular film that has been sung praises in both critical and fan-savvy ways on its later run.
