Supergirl – Have Fun on a New Planet!
TYPE OF ACTIVITY: Interactive games, immersion, exhibition, epic photo
ACTIVATION DESCRIPTION
Get ready to venture into Supergirl’s intergalactic bar. Relax, relax — she’s not the owner of the bar (though she totally could be). Enjoy the Krypto Challenge, take lots of photos with our out-of-this-world popcorn machine, compete against your friends in Kryptonian speed and strength battles, and dance to our greatest hits.
Stay alert so you don’t miss the chance to win prizes in the claw machine — good luck!
A “super” marketing campaign, similar to James Gunn‘s Superman, is being planned for Supergirl. Lobo is expected to play a major role in the campaign, which is set to launch at CCXP 2025.
Recently, an official Supergirl account has also become active on Instagram as part of the film’s promotion and the upcoming trailer release.
What is the plot of Supergirl?
While celebrating her 21st birthday, Kara Zor-El (Milly Alcock), feeling lost and purposeless, travels across the galaxy with her dog Krypto. Along the way, she meets Ruthye Marye Knoll (Eve Ridley), a young alien girl seeking revenge on the warlord Krem (Matthias Schoenaerts), who killed her father. Their journey takes Kara to a planet with a red sun, stripping her of her powers and forcing her to discover what it truly means to be a hero without her superhuman abilities.

Directed by Craig Gillespie, from a screenplay by Ana Nogueira and based on the comic by Tom King and Evely, the film will serve as the second entry in the DC Universe and the fourth installment of Chapter One: Gods and Monsters.
The film stars Milly Alcock as Kara Zor-El / Supergirl, Matthias Schoenaerts as Krem of the Yellow Hills, Eve Ridley as Ruthye Marye Knoll, David Krumholtz as Zor-El, Emily Beecham as Alura In-Ze, Jason Momoa making a cameo appearance as Lobo, and Ferdinand Kingsley cast as Elias Knoll, Ruthye’s father.
James Gunn and Peter Safran are producing the film, with DC EVP Chantal Nong serving as the executive producer.
Supergirl will hit theaters in the United States on June 26, 2026, by Warner Bros. Pictures.
