In a strange bit of synchronicity (or more likely a simple game of chicken between movie studios), May 21, 2021 was previously announced as the release date for John Wick: Chapter 4 which also stars Keanu Reeves.
Either way: The Matrix 4 has an official release date.
While this sounds like news that could only occur in a lifelike simulation of reality, it is in fact real.
Today, Warner Bros. announced it was slotting this fourth Matrix film for a May 21, 2021 release.
