Henry Cavill, who has played Superman in three films, is parting ways with Warner Bros.
Talks broke down for a cameo in 'Shazam!' due to scheduling conflicts.
The door is now closing on other potential appearances for the actor.
The studio has shifted its focus to a Supergirl movie. Superman, aka Kal-El, would be an infant.
Warners isn't likely to make a solo Superman film for at least several years.
