And then added an update.

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

Casting announcements may be imminent. So far, all we know is Dwayne Johnson's Black Adam will not appear (except for a possible cameo), Sandberg has shown signs he is more influenced by the classic version of Captain Marvel rather than the Curse of Shazam reboot, and has said he will cast two actors as Billy Batson and Captain Marvel, instead of casting only one, and using CGI trickery to create the other.
