An avid comic book fan since she first read "Stan Lee's Soapbox," Allison Hambrick is your friendly neighborhood generalist writer. Journalism, editing, media production, copywriting—she does it all. From her very first blog post about Smallville as a primary schooler, Allison developed a passion for superheroes and the entertainment industry at large.

Majoring in writing and film at SCAD, Allison put her skills to work writing, editing, podcasting, and more. Currently, she moonlights as an editor at the ASHRAE Journal by day and Screen Rant by night. Allison also previously worked for Warner Bros. Entertainment and for Disney.

Through her writing, she hopes to inspire, to entertain, and to empower others to be the best versions of themselves, and her mission in life is to make Stan proud. In her free time, she enjoys reading, video game design, traveling, and spending time outside with her dogs, Loki and Elphaba. Allison is fluent in movie quotes, and her favorite film is Superman II.

With less than half a year to its June release, Supergirl is one of the most anticipated movies of 2026. Following the blockbuster success of Superman, it continues James Gunn and Peter Safran's newly minted DC Universe with a very different protagonist. Directed by Craig Gillespie, Supergirl stars Milly Alcock as the titular hero, as well as Jason Momoa, David Krumholtz, Emily Beecham, Matthias Schoenaerts, and Eve Ridley.

Though Kara Zor-El is Superman's cousin, she is a hero all her own, and her story is set to take fans to the broader galaxy of the DCU. As such, Gunn addressed the similarities between the film and his previous intergalactic trilogy of Guardians of the Galaxy films. The DC Studios boss told Variety: "I think it’s a space fantasy, which is like ‘Guardians’ in a way, but it’s based on the Tom King book, but it doesn’t follow it religiously, but it has a lot of the core of that there.

"I’m really excited for people to see it and to see Milly," Gunn continued. "It’s going to be awesome." Elsewhere in the interview, the DC Studios co-CEO also addressed the future of the DCU amid the proposed Netflix buyout of Warner Brothers Discovery.

Do I have hopes?" Gunn explained. "No, I really don’t because everything’s unknown." Despite the fate of Warner Brothers being up in the air, he finds the opportunity to work with the new parent company "really exciting," opting to "hope and pray for the best."

"I’ve been through these sorts of changes so many times that I’ll always be careful what you wish for because you don’t really know until you know," he concluded. "And I hope it goes well, and I think it’s exciting, you know, every direction has really exciting things for DC, so I’m excited about where it’s going to go."

For Gunn, the excitement of bringing the DCU to live traces back to his lifelong love of superheroes. "Being able to shepherd these characters into the next stages of their existence in media is a privilege," the director added. "It’s exciting to help create the next wave, the way people see them today."
