The poster features Milly Alcock, Woman of Tomorrow, with the getup of Supergirl and wearing a overcoat over her dress. She can be see drinking a Slurpee, standing next to a Superman poster. The caption in the post read: "Look Out. 2026."

Hot off the heels of the blockbuster success of Superman, DC Studios is ready to introduce us to another child of Krypton already. After tiny teases throughout its production, we have our first proper look at Milly Alcock’s Supergirl.

The Supergirl film, titled Woman of Tomorrow, also stars Matthias Schoenaerts, Eve Ridley, David Krumholtz, and Emily Beecham. Fans reacted excitedly to the poster. One commented, “I loved her cameo at the end.

Supergirl comes in for a landing. James Gunn officially released an image of the Supergirl suit after Milly Alcock's big-screen debut.

Milly Alcock is known for her portrayal in House of the Dragon. She has recently made a brief appearance in David Corenswet's Superman Kara Zor-El, cousin of Kal-El aka Clark Kent.

Milly Alcock's Supergirl has a brief but hilariously memorable cameo in James Gunn's Superman, establishing her party girl persona along with the basic facts that she's Superman's cousin, and that she's been off-world. And as we see in the movie, the DCU's Kara Zor-El is what James Gunn tells ScreenRant is a "total mess."

Released yesterday (July 16) by DC Studios co-chief James Gunn, it shows the eponymous hero sipping on a Slurpie as she poses next to the immediately recognizable 'S' symbol that adorns her and fellow Kryptonian Superman 's outfits.
