‘Supergirl’ Trailer Date Rumored as New Casting Announcement Made

by

December is shaping up to be a big month for movie trailers. We’re expecting the first looks at trailers for films like Avengers: Doomsday and Masters of the Universe before Avatar: Fire and Ash hits theaters. Now, it seems James Gunn’s DC Universe might also be joining the excitement, with a trailer for a film planned for next summer reportedly arriving in two weeks. This news comes alongside more announcements about the movie’s cast, which will be revealed further at the CCXP event in Brazil next week.

Summer 2026 will see the release of several eagerly awaited films, and Supergirl is one of the most important. A lot of pressure is on star Milly Alcock, as Superman didn’t fully convince everyone that James Gunn can successfully revitalize the Warner Bros. DC universe. The success of Supergirl will be carefully observed, not only by moviegoers but also by those considering a potential takeover of Warner Bros.

Originally, the HBO Max series Lanterns was planned to come out before Milly Alcock’s first full appearance as Supergirl’s cousin. However, due to delays with Lanterns, Supergirl is now the next DC Universe project scheduled for release. The show already has a strong cast including Alcock, Eve Ridley as Ruthye Marye Knoll, Matthias Schoenaerts as Krem of the Yellow Hills, Jason Momoa as Lobo, David Krumholtz as Zor-El, and Emily Beecham as Alura In-Ze. Ferdinand Kingsley, known for Silo, has now joined the cast as Elias Knoll, Ruthye’s father.

‘Supergirl’s Marketing Is Already Firing Up

Even though we won’t see Milly Alcock in the new movie for at least six months, an official-looking social media account for the film has already appeared. It’s likely the real account, as its username is simply @supergirl, and it seems to be preparing for announcements and previews at the upcoming CCXP event.

CCXP is coming up, and fans are hoping for some exciting announcements. In the past, the event has delivered big reveals like trailers for films such as Wonder Woman 1984 and Godzilla vs. Kong, but more recently it’s been quieter, with only new posters being shown. It’s possible DC will use CCXP to generate buzz for Supergirl before Marvel potentially overshadows them with a preview of Doomsday. We’ll have to wait and see what happens.

Details about the upcoming Supergirl movie have largely come from AI-generated sources, but what we know for sure is that the film will follow Supergirl and her dog, Krypto, as they journey across the galaxy to celebrate her 21st birthday. During their travels, they’ll meet a woman named Ruthye who will involve Supergirl in a dangerous quest for revenge.

There’s a lot of excitement building for the new film, especially with Jason Momoa joining the cast. He’s been wanting to play the character Lobo for years, and now he’s finally getting the chance! Fans are eager to see the first images of both Momoa as Lobo and the film’s lead heroine, played by Alcock, in action.
