As Warner Bros. move their upcoming blockbuster film release dates around, The Batman has unfortunately been pushed back from October 2021 to March 2022.
The move arrives after Denis Villeneuve's Dune takes Batman's original October slot, while The Flash and the Shazam! sequel are also consequently being delayed, too (the former will debut on November 4, 2021, while the latter is set to premiere on June 2, 2023).
It's not all delays, though, and The Matrix 4 has reportedly been moved forwards from April 2022 to December 22, 2021.
