Hollywood Reporter told DC Fans today that Henry Cavill may no longer be Superman because of the possible Supergirl film?
But contract talks between Cavill's WME reps and Warners broke down, and the door is now closing on other potential Superman appearances.
That's because the studio has shifted its focus to a Supergirl movie, which will be an origin story featuring a teen superheroine. This effectively removes an actor of Cavill's age from the storyline's equation given that Superman, aka Kal-El, would be an infant, according to DC lore.
Furthermore, Warners isn't likely to make a solo Superman film for at least several years, according to another source. "Superman is like James Bond, and after a certain run you have to look at new actors," says a studio source. As such, Cavill will join Ben Affleck, who isn't expected to reprise his role for director Matt Reeves' forthcoming Batman stand-alone film, as a hero on the way out.
