American superhero film Supergirl is out now in theatres.

Kara Zor-El/Supergirl (Milly Alcock) celebrates her 23rd birthday by travelling across the galaxy with her dog Krypto.

Along the way, she meets Ruthye Marye Knoll (Eve Ridley) and, upon learning about the young girl’s father who died at the hands of space pirate and bounty hunter Krem of the Yellow Hills (Matthias Schoenaerts), the two join forces on an interstellar journey of vengeance and justice.

The film serves as the second instalment in the DC Universe (DCU) franchise. It is a newly created production entity under Warner Brothers Discovery, co-chaired by film director James Gunn and producer Peter Safran, dissolving its predecessor DC Films in 2022.

The movie follows Superman (2025), which included a first look and cameo of Milly’s Supergirl, starring David Corenswet, who is also reprising his role as Clark Kent/Superman and Kara’s cousin who was sent away from Krypton as an infant and lives on Earth as a superhero.

Unlike Clark, Kara stayed back and watched everyone around her die, making her a jaded person who feels no duty to save or rescue others.

However, meeting Ruthye, who has also endured tragedy, gives her purpose and snaps her out of the destructive cycle.

“Through helping save this young girl and deal with her trauma from losing her entire family, there’s a kinship there,” Milly said in an interview.

“She realises that being Supergirl has nothing to do with her and has to do with everybody else around her. She needs to put her own feelings aside to help others, and through that she can save herself. So that’s what the suit is for her,” she added.
