Shazam! director David F. Sandberg has signaled the beginning of pre-production with a pair of photos from his new office on the Warner Bros. studio lot.

Fans seeking for revelations about the long-developing film won't find them in Sandberg's snapshots. They instead chart his soda consumption on the first day of pre-production.

Day 2. On this movie I might get to the ceiling. Or the hospital.

The photos would seem to confirm comments earlier this month by Sandberg (Annabelle: Creation) that Shazam! will be the next DC Comics-based film to move into production, following James Wan's Aquaman.

In development at New Line as far back as the early 2000s, Shazam! passed through the hands of a half-dozen or more screenwriters over the years. The adaptation seemingly gained steam around 2009, only to quickly falter due to what one-time director Peter Segal attributed to the resurgence of Superman on the big screen. However, just when it looked as if Shazam! was dead, the film appeared in 2014 on Warner Bros.’ initial slate of DC Comics films.

Dwayne Johnson was long attached to Shazam!, ultimately settling in 2014 on the role of the hero's longtime foe Black Adam. However, it was announced in January that Johnson won't appear in Shazam! but will instead star in a separate Black Adam movie.

No casting has been announced for Shazam!, which is targeting a 2019 release.
