The DC Extended Universe (DCEU) media franchise experienced a turbulent history since its inception in 2013, characterized by highly publicized clashes between studio executives and talent, constantly changing approaches to worldbuilding, and repeated changes in management. Warner Bros. Pictures originally announced plans for a shared universe of live-action films based on the DC Comics, starting with the release of Man of Steel (2013), with director Zack Snyder set to spearhead the franchise. Following the negative reception to Snyder's follow-up film Batman v Superman: Dawn of Justice (2016), Warner Bros. created DC Films, a new division led by Geoff Johns and Jon Berg tasked with overseeing development of the DCEU. DC Films attempted to correct the course of the franchise, culminating in the troubled production and disastrous release of the crossover film Justice League (2017), which significantly deviated from Snyder's original vision.
