DC is going to release a series of one-shots in the run-up to the Black Adam movie's release. Each one is going feature one of the JSA characters that'll appear in the movie.
The first one up is Hawkman, which will be titled "Black Adam–The Justice Society Files: Hawkman #1" and releases Tuesday, July 5th.
I'm excited for the Atom-Smasher one-shot and the Doctor Fate one-shot, though I admit I don't have high expectations for movie tie-ins, but they'll still give me a feel for the movie's take on the characters (and tone)
