Thrilled to see cameras roll at Warner Bros. Studios Leavesden on Supergirl, with Craig Gillespie at the helm and the phenomenal Milly Alcock as our Kara Zor-El. Craig brings an incredible sensibility to this story, and Milly is every inch the unique #Supergirl envisioned by Tom… pic.twitter.com/za9Tr8Vryr

James Gunn gave DC Comics fans their first look at Milly Alcock’s take on classic character Supergirl today. Well, our first look at her back. Well, our first look at part of the back of her head. Still, you can already hear those John Williams trumpets a-blowin’!

In a post on Bluesky, Gunn announced that cameras have begun to roll on Supergirl: Woman of Tomorrow starring House of the Dragon's Milly Alcock as Kara Zor-El aka Supergirl. He also shared a photo of Alcock sitting in her actor's chair, so technnically it's a first look at the character.
