Warner Bros.' The Flash opened to $55 million domestically, a disaster for the studio. The Flash has many flaws, but fans love Sasha Calle's Supergirl.
Calle's reaction to being cast as Supergirl, a.k.a. Kara Zor-El, was one of the film's most touching moments before The Flash became so controversial.
The Flash stars Calle, Ezra Miller as the Flash, Michael Keaton and Ben Affleck as Batman,
Given the film's reception and dismal box office, this may be Calle's only Supergirl appearance.
