A sequel to the soon-to-be-released The Flash may not have been announced yet, but Warner Bros. has reportedly been keeping a completed script under wraps.
According to Variety, the studio already has a "finished" sequel script from Aquaman screenwriter David Leslie Johnson-McGoldrick, though they "never announced it". The report says that the script features appearances from Michael Keaton's Batman and Sasha Calle's Supergirl, who star in the original movie alongside Ezra Miller's titular speedster.
