In addition to Milly Alcock, actors Emilia Jones (“CODA”) and Meg Donnelly (“The Winchesters”) are also reportedly being considered for the role of Kara Zor-El in the DCU. Unlike Jones and Alcock, Donnelly has already played Supergirl. To date, she’s voiced the character in two animated films: 2023’s “Legion of Super-Heroes” and this year’s “Justice League: Crisis on Infinite Earths — Part One.”
Her familiarity with the comic book hero doesn’t mean that Donnelly is any more likely to be cast as Supergirl than her fellow contenders for the role. Alcock is, after all, arguably the most well-known of the three actors, having received widespread attention in 2022 for her performance as Rhaenyra Targaryen in the first half of “House of the Dragon” Season 1. As the above fan art proves, it wouldn’t take much for her to nail Supergirl’s look onscreen either.
Fans, of course, won’t know whether Alcock has been cast as Clark Kent’s Kryptonian cousin until James Gunn makes an official announcement one way or the other. No matter who ends up playing the DCU’s Supergirl, though, fans shouldn’t expect the character to be too similar to David Corenswet’s Superman. At least, that’s what Gunn suggested when he discussed “Supergirl: Woman of Tomorrow” in 2023, teasing, “In this story, she is a character who was raised on a chunk of Krypton. She watched everybody around her perish in some terrible way, so she’s a much more jaded character.”
Whoever portrays Supergirl next will, in other words, likely have to pull off a very different version of Kara Zor-El than most viewers may expect.
