“Supergirl,” starring Milly Alcock in the title role, will try to find a new audience on digital streaming this week following a dismal run at the box office.
Alcock, of course, appeared in a cameo turn at the end of director James Gunn’s Superman, starring David Corenswet, in July 2025. In Supergirl, Alcock’s character, who is Superman’s cousin Kara Zor-El, is featured in the lead while Corenswet appears in a small supporting role.
