The True Blood reboot has seemingly been canceled at HBO amidst Warner Bros. Discovery's cost-cutting measures. Created by Alan Ball, the Southern vampire drama aired on HBO from 2008 to 2014 for seven seasons of runaway success. In December 2020, it was reported that a True Blood reboot was in development from Ball and Riverdale showrunner Roberto Aguirre-Sacasa. In the following years, there have been a few updates indicating the True Blood reboot has had trouble getting off the ground.
