After the DC Universe reboot and the blockbuster success of the 2025 Superman movie, the hype for upcoming DC Universe films is at an all-time high. One of the most anticipated projects is Supergirl, which is set to release on June 26, 2026. With Supergirl entering the DC Universe, the possibilities for major superhero crossovers have significantly expanded.
After debuting in Superman (2025), Milly Alcock will reprise her role as Kara Zor-El / Supergirl in her standalone movie, directed by Craig Gillespie. The film’s cast includes Eve Ridley, Matthias Schoenaerts, David Krumholtz, Emily Beecham, and Jason Momoa. Momoa will make his live-action debut as the DC character Lobo, marking a major crossover moment for the franchise. David Corenswet is also expected to appear in a cameo as Superman, further strengthening DCU continuity.
During an interview in Mexico, Milly Alcock reacted to future crossover possibilities, saying she hadn’t really thought about it before, but now the idea excites her—especially thinking about which characters Kara might meet in the future.
Although Supergirl hasn’t directly suggested her ideal crossover, there are already several clear possibilities within the DC Universe. In Superman, Skyler Gisondo’s Jimmy Olsen and Kara both appear, but interestingly, they don’t share any scenes. By the end of that film, Jimmy Olsen is shown in an unusual relationship with Eve Teschmacher.
In comics and previous adaptations, Jimmy Olsen and Kara Zor-El have shared a strong connection—sometimes as friends, sometimes with romantic undertones. This dynamic was also explored in Supergirl, Smallville, and My Adventures with Superman. Because of this, their interaction in the DCU seems like a natural progression.
Additionally, in the comics, Kara has connections with other iconic heroes like Nightwing, who is rumored to appear in the DCU. Another possibility is Kara becoming part of the “Justice Gang,” a concept teased in Peacemaker Season 2. Ultimately, Supergirl will further integrate Kara Zor-El into the DCU, opening the door to a wide range of crossover opportunities—whether with Jimmy Olsen, Superman, or new heroes.
Supergirl is being portrayed in a fresh direction in the DC Universe. Milly Alcock’s Kara Zor-El is introduced as the last daughter of Krypton and Superman’s cousin. This isn’t the first live-action portrayal of Supergirl—Helen Slater played the character in the 1984 Supergirl film, and Sasha Calle portrayed her in The Flash.
In her interview, Milly Alcock mentioned that this version of Kara has been approached with a unique and independent identity. According to her, this Supergirl is very different from previous female superheroes. She described the character as having a sense of “rawness and realness” that hasn’t been seen much before. Kara is messy, slightly rebellious, and has a cool, cheeky personality. This portrayal makes her feel more grounded and human rather than a perfectly polished superhero.
It’s clear that Supergirl is shaping up to be one of the most complex characters in the DC Universe. When Kara Zor-El is introduced in Superman, she is in a very different mental state compared to her fellow Kryptonian. While Superman has accepted his Clark Kent identity and is living a balanced life, Kara is still searching for her purpose.
She has lost almost everything and everyone in her life, which leaves her emotionally unstable and directionless. Director Craig Gillespie found this contrast interesting from the beginning, as it highlights not just a difference in power between Superman and Supergirl, but also in emotional maturity and identity.
Kara’s journey is more internal—she isn’t just trying to become a hero, but also trying to understand the meaning of her existence.
In the DC Universe, Supergirl is being presented as an emotionally complex and flawed protagonist. Director Craig Gillespie, known for films like I, Tonya and Cruella, found Kara Zor-El compelling from the very first script reading.
Milly Alcock’s introduction as Kara establishes that she is not a “perfect hero,” but a flawed character shaped by trauma and loss. According to Gillespie, this makes her journey very different from Superman’s—while he has already accepted his identity, Kara is still searching for hers.
This complexity is what interested the director the most, as it allows for a balance of humor and emotional depth. He even mentioned that he accepted the project after reading just a few scenes.
In terms of story, the film follows Kara on a dangerous cosmic journey after her beloved dog Krypto is poisoned. Along the way, she is joined by Lobo and Eve Ridley’s character, Ruthye Marye Knoll, who is on a mission to avenge her father’s death.
Craig Gillespie described the production as a long and collaborative process, and he is eager for audiences to see Milly Alcock’s performance, which presents Kara Zor-El in a new, emotionally grounded way.
Now, how this Supergirl movie will introduce new female superheroes and expand crossover possibilities will only be clear after its release on June 26.
