Justice League, Batman v Superman: Dawn of Justice, Wonder Woman, Suicide Squad, Batman, Batman Returns, Batman Forever, Batman & Robin, Catwoman, Jonah Hex, and The Losers are all on their way out on July 1st, as it the hit animated film The LEGO Batman Movie. This isn't hidden information, either. If you click on any of these titles on HBO Max, you'll see the "Available until Jul 1, 2020" message right below their description.
The only DC movies sticking around past July 1st are Aquaman, Shazam!, Joker, Green Lantern, and Supergirl. That's a pretty short list compared to those that are leaving.
