The final trailer for Supergirl just dropped, and it puts Kara Zor-El in a race against time. Milly Alcock takes on the role of Superman’s cousin, but this version of the character is far from the cheerful hero fans remember. She is angry, alone, and willing to do whatever it takes to save the one living thing she cares about—her dog, Krypto. The trailer, released on June 2, 2026, shows David Corenswet returning as Superman, Jason Momoa debuting as the fan-favorite antihero Lobo, and a ticking clock that decides Krypto’s fate.
Krypto Gets Poisoned, Giving Kara a Three-Day Deadline
The most talked-about moment in the trailer is the attack on Krypto the Superdog. The villain, Krem of the Yellow Hills (played by Matthias Schoenaerts), shoots Krypto with a poisoned bolt while escaping. A healer tells Kara that the brigands always carry an antidote, but Krypto only has three days to live without it.
This changes the game completely. Kara is not just hunting a killer for revenge. She is fighting against the clock to save her best friend. In the comics, Krypto also gets poisoned, but there is no clear timeline for his recovery. The movie adds this countdown to raise the stakes and push Kara into action faster.
The trailer makes it clear that Krypto is Kara’s only real family. She tells Superman, “He sees the good in everyone. And I see the truth.” While Clark tries to convince her to find “her people,” she refuses, saying, “I have no people.” The only companion she truly trusts is Krypto.
Superman Tries to Help, But Kara Walks Alone
David Corenswet appears as Clark Kent/Superman in the trailer, and the difference between the two cousins is clear. Superman is the optimist. He believes in humanity and tries to guide Kara. But Kara has seen too much pain. She lost her entire planet, Krypton, and grew up watching her family die. She did not arrive on Earth as a baby like Clark. She remembers everything.
The trailer shows Clark leaving voicemails for Kara, asking where she is and if she is okay. She ignores them. When he finally finds her, he tries to give her a new supersuit as a gift. But Kara does not want to be a symbol of hope. She wants to be left alone—until Krypto gets hurt.
James Gunn shared the final trailer on X (formerly Twitter) and confirmed that tickets are now on sale in the United States. The film will also play in IMAX theaters.
Jason Momoa’s Lobo Finally Arrives
Jason Momoa has wanted to play Lobo for years. Back in 2023, he said in an interview with Fandango, “If they call and ask me to play him, it’s a f*** yeah.” When DC bosses *James Gunn* and Peter Safran released the cast list, Momoa simply posted on Instagram: “They called.” Now the trailer confirms the worst-kept secret in Hollywood.
Lobo is an intergalactic bounty hunter with a rough attitude, white face paint, and a love for violence. The trailer shows him fighting alongside Kara, though it is clear they are not friends. Fans on Reddit celebrated the casting. One user wrote, “Perfect casting, is just peak.” Another said, “The main man himself.”
The Story Follows ‘Supergirl: Woman of Tomorrow’
The movie is based on the comic series Supergirl: Woman of Tomorrow, written by Tom King with art by Bilquis Evely. In the original story, a young alien girl named Ruthye Marye Knoll (played by Eve Ridley) loses her father to Krem. She hunts down Supergirl to help her get revenge. The trailer follows this setup closely, but with one major change: Krypto’s life is now on a timer.
Ana Nogueira wrote the screenplay, and Craig Gillespie directs. The cast also includes David Krumholtz as Zor-El and Emily Beechum as Alura.
Fans Compare the Trailer to Guardians of the Galaxy
Not everyone is happy with the trailer’s look. Some fans on social media pointed out that the colorful space settings, rock music, and talking animal sidekick feel similar to Marvel’s Guardians of the Galaxy. One viral post called it “Guardians of the Galaxy 3.5.” Another user wrote, “It just looks like a Guardians of the Galaxy spin-off. Doesn’t look or feel like Supergirl at all.”
But defenders of the movie say the comic book came first. Supergirl: Woman of Tomorrow was published in 2021 and 2022, before some of the comparisons being made. The story has always been a space western with a bitter hero and a young companion. The movie is simply staying true to the source material.
Milly Alcock Speaks About Fame and Criticism
Milly Alcock, who became famous playing young Rhaenyra Targaryen on House of the Dragon, knows the spotlight comes with harsh comments. In an interview with The Hollywood Reporter, she talked about how women in the public eye face constant criticism.
“It definitely made me aware that simply existing as a woman in that space is something that people comment on. We have become very comfortable having this weird ownership of women’s bodies. I can’t really stop them. I can only be myself.”
She also admitted that seeing her face on social media makes her anxious. “No one should have to do that. It fuckin’ sucks, man. I don’t know how the socialites of the world can do that,” she said.
When asked about famous directors like Martin Scorsese and Ridley Scott who have criticized superhero movies, Alcock took a simple approach.
“I get it. They’ve been around for fucking ever making phenomenal films. … Not every film is for everyone. The beauty of art is that you can be selective.”
