Barry Allen might be the fastest man in the world but when it comes to getting his movie onto the big screen he couldn't be slower. The Flash has been the problem child of the already extremely problematic DC Universe. The movie was first announced in 2014 but has since gone through multiple directors and has been delayed multiple times. There have been talks as to whether or not the movie was even going to happen or in what state it was going to arrive in. When The Flash was announced DC and Warner Bros. were planning their own version of the Marvel Cinematic Universe. However, things have changed considerably since then. The last we heard was that Andy Muschietti was going to direct the movie but there hasn't been much movement since then.
It seems that Warner Bros. is once again confident enough that this production will get off of the ground as according to The Hollywood Reporter, The Flash now has July 1, 2022 release date. It's going to be a special effects-heavy movie so we should expect production to start sometime in 2020 or very early 2021 at the absolute latest. However, this is one of those movies where no one is really sure it's going to happen until we're still in a theater on opening day.
Warner Bros. didn't stop there. The Matrix 4 has come out of nowhere and is getting turned around really fast. There has been a lot of casting going on in recent months and Warner Bros. has given the movie a May 21, 2021 release date. That isn't that far away and we can expect production on this to start very soon. That release date is notable for two reasons. That was the original release date for the Taika Waititi directed remake of Akira which has been officially removed from the release schedule. It's also the same day that John Wick: Chapter 4 is set to come out. So no matter how that weekend is going to go Keanu Reeves is going to have a good day.
Finally, Warner Br0s. has also moved the release date for Mortal Kombat up to January 15, 2021, which is not a great sign for that movie. January is infamously one of the places studios drop movies they know are going to be duds. Maybe this one will buck the trend.
