Not much has been said as of late regarding the Shazam movie other than Dwayne Johnson stating it's going to happen sooner rather than later. Shazam is also being released under WB's New Line Cinema wing and seems to be more independent of the Justice League movies. No director is attached, and it's thought Shazam may be released in 2019 (or sooner according to Johnson's words).
Toby Emmerich, president of New Line, did offer the following back in May:
“[Shazam! is] a DC comic, but it’s not a Justice League character, and it’s not a Marvel comic. The tone and the feeling of the movie will be different from the other range of comic book movies. [It] will have a sense of fun and a sense of humor. But the stakes have to be real.”
Shazam has also been described as "bad ass fun" by a producer on the movie.
