After appearing in the Superman movie, Milly will next star in her own movie, Supergirl: Woman of Tomorrow.

“This is a very different type of Supergirl,” James Gunn said (via TheWrap). “In our [film], we see the difference between Superman, who was sent to Earth and raised by loving parents from, you know, the time he’s an infant, versus Supergirl, who was raised on a rock chip-off of Krypton and watched everyone around her die and be killed in terrible ways for the first 14 years of her life, and then came to Earth when she was a young girl and is much more hardcore. She’s not exactly the Supergirl we’re used to seeing.”

Other actresses considered for the role included Emilia Jones and Meg Donnelly.
