Supergirl Goes Full-On John Wick In New Trailer

The latest trailer for Supergirl, starring Milly Alcock, Jason Momoa, and Eve Ridley, has been released, and I take back everything I said about the previous teaser trailer. Everything about the old trailer indicated a disrespect for the Superman source material and a rebellious girl-boss operating under the slogan, “Truth. Justice. Whatever.”

Yet the new trailer, released March 31, 2026, reveals a lot more about the plot and the source of Supergirl’s anger. A story that was indicated to be about Kara, aka Supergirl, helping an alien girl named Ruthye avenge the death of her father becomes much more poignant when you know that the murderer has also poisoned Krypto, Supergirl’s faithful canine that she’s had since her days on Krypton.

Supergirl’s John Wick Arc

The dog is all she has left of her former home, since Kal-El is more like a human from living on Earth since infancy. Kara is a young girl grieving and literally the only person she knows who remembers her planet. Under those circumstances, she’d probably tell us to get over any problems we might have with her rebelliousness, and her John Wick reaction is just as forgivable as with the Keanu Reeves hitman.

The girl power theme from the previous trailer can now be forgiven now that we know the director is Craig Gillespie, famous for The Powerpuff Girls. Supergirl seems to ask the question, “What if Buttercup from The Powerpuff Girls grew up, lost everything in Townsville, and is now in a race against time to save her beloved pet?” Ruthye seems to stand in as a demure Blossom, and there’s probably enough of Bubbles to go around for both of them. The style of the movie is signature Gillespie, a live-action rendering of his cartoon universes.

Jason Momoa Brings The Boom

There’s also plenty of room for the boys. Superman makes an actual appearance this time, rather than having his picture peed on by Krypto, and it is clear that he is worried about his cousin. He wants her to embrace the planet as he has, but she isn’t having any of it because she is too bitter about losing Krypton.

However, the objective highlight of the trailer is Jason Momoa as Lobo. If there was any actor born to play this role, it was Momoa, who looks exactly like his comic book counterpart. His perfectly fitting appearance is nothing compared to what we get to see of his performance during this trailer as he rolls in on his skull-adorned chopper to trade barbs with the movie’s heroine. If this trailer is any indication of what his performance is going to be like, it won’t be long before fans are clamoring for a stand-alone spinoff movie centered on Lobo.

Filled with color that hasn’t been dampened by sepia, bright explosions, and really cool outer space scenes, Supergirl looks a lot more promising the second time around than it did the first. Hopefully, it delivers on the promises of its trailer.
