Lobo’s role in Supergirl, explained
We don’t know whether Supergirl will be a direct, page-for-page adaptation of ‘Woman of Tomorrow’, but one of 2026’s most exciting new movies will feature a small but highly significant change to the story depicted in the source material?
The alteration in question? Lobo’s inclusion. The fan-favorite bounty hunter was, according to ‘Woman of Tomorrow’ writer Tom King, originally going to be part of the graphic novel. However, speaking to comicbook.com, King revealed he was omitted at the request of his editors.
With Jason Momoa set to portray Lobo in Supergirl, will the comic book flick include those cut story elements? Again, that’s unclear, but Gunn has teased the vital role that Lobo will play in Supergirl.
“[‘Supergirl:]Woman of Tomorrow’ is a bunch of little stories,” Gunn told the Official DC Studios podcast in June. “And, we needed to create one through-line, one three-act, more traditional story. So, Lobo helps us to do that.
“I love Lobo,” he continued. “I always thought he was a great character to adapt and, maybe, in some way, the biggest comic book character that’s never been in a film. So, I think it was a cool thing to do [include him in Supergirl].”
Who’s joining Milly Alcock as part of the Supergirl cast?

‘Supergirl: Woman of Tomorrow’ might be primarily billed as a space opera by some readers, but it’s also an intimate drama-cum-character study with only a handful of notably named individuals.
So, which other actors are going to appear as part of the DCU Chapter One movie’s cast? My Supergirl cast and character guide discusses the stars who’ll show up, which characters they’re playing, and where you may have seen them before. If you want a quick rundown on its tight ensemble, though, read the list below:
- Milly Alcock as Kara Zor-El/Supergirl
- Eve Ridley as Ruthye Marye Knoll
- Matthias Schoenaerts as Krem of the Yellow Hills
- Jason Momoa as Lobo
- David Krumholtz as Zor-El
- Emily Beecham as Alura In-Ze
- Ferdinand Kingsley as Elias Knoll
‘I thought ‘What have I done?”
That’s not to say Alcock fully believed she was the right fit for one of DC Comics’ beloved superheroes. Indeed, speaking earlier this month, Alcock revealed why she panicked after being cast as the DCU’s Supergirl.
“I thought, ‘what have I done?'” she recounted in an interview with Forbes magazine. “I really struggled to believe I could do it. I even called the director [Craig Gillespie] saying ‘I don’t know how to be that person. I’m just me’.
“Eventually, I realized the only way through was to trust myself,” Alcock added. “I always believe life is right on time. Things happen when they’re supposed to, whether you feel ready or not.”
For what it’s worth, James Gunn has gushed about Alcock’s performance as Supergirl, with the DC Studios co-chief telling The Howard Stern Show: “Milly Alcock, who plays Supergirl, might be the best bit of casting I think I’ve ever done in my entire life. She’s absolutely stunning in the movie”. High praise indeed from an industry veteran who’s worked with plenty of actors throughout his career.
Who’s playing Kara Zor-El in Supergirl?
Aaaaaand I’m back. Now, what was I going to talk about next… ah, yes, the lead star of Supergirl: Milly Alcock.
Anyway, if you’re wondering where you might have seen Alcock before, she got her big break (in the US, anyway) playing the child/teenage version of Rhaenyra Targaryen in House of the Dragon, HBO’s live-action take on George R.R. Martin’s Game of Thrones prequel novel.
Since then, the Australian actor has appeared in Netflix drama Sirens and made a scene-stealing cameo as Supergirl in Superman. Where the latter is concerned, Alcock’s cameo in Superman was all I needed to have full confidence in her take on Supergirl, too.
Anyway, the rest of her C.V. comprises projects from Down Under, including The Gloaming, Upright, Reckoning, and Fighting Season. In short: the 25-year-old had plenty of experience to call upon after landing this role.
Takin’ a break
Alright, time for this UK native to take a quick lunch break. I’ll run you through more of my Supergirl coverage, as well as some other news and rumors, upon my return.
Feel free to talk amongst yourselves or, if you want to get a head start on things I’ll discuss later on, check out my dedicated Supergirl guide for more on its cast, story, and potential DCU impact.
Plotting out its story
Of course, there are a couple of things we know about Kara Zor-El’s first big-screen adventure in over 40 years.
For starters, it’s drawn heavily from ‘Supergirl: Woman of Tomorrow’. That’s the comic book series from Tom King, Bilquis Evely, and Matheus Lopes that fans and critics alike have raved about since the first of its eight issues was released in June 2021.
I won’t start getting into the finer details of the graphic novel’s plot here because, well, spoilers. However, DC Studios has revealed the movie’s story synopsis. So, if you want a very brief overview of its narrative, here you go: “When an unexpected and ruthless adversary strikes too close to home, Kara Zor-El, aka Supergirl, reluctantly joins forces with an unlikely companion on an epic, interstellar journey of vengeance and justice.”
What will wee see in Supergirl’s first teaser?
I can’t say for sure. However, Monday’s the 10-second teaser, plus another 15-second montage that went live on Supergirl‘s various social media channels yesterday, have given us a sense of what to expect.
The latter video, which you can watch above, contains bite-sized clips of the likely extended footage we’ll see in the forthcoming trailer. It certainly gives off an air that it’ll have more attitude than this year’s Superman film but, until the teaser is with us, there’s no telling how much of its story it’ll, well, tease.
Still, I’ve drawn up a wish list of three things I want Supergirl‘s first trailer to contain – and one I don’t. So, check that out if you’re curious to see what my predictions are for it.
A super day to be a Supergirl fan
So, how are we feeling today? I’m very excited – and, truth be told, I have been since DC Studios released the first albeit brief teaser for Supergirl on Monday and confirmed its first official trailer would drop sometime this week.
We didn’t have to wait long to learn what day it would drop, either. Yesterday (December 10), DC announced Supergirl‘s first trailer would take flight today – i.e. Thursday, December 11. It’ll premiere at 9am PT / 12pm ET / 5pm GMT / 9:30pm IST, too.
For those of you based in Singapore, Australia, and New Zealand, you’ll have to get up early tomorrow if you want to watch it soon as it lands. Indeed, the aforementioned 9am PT launch means it’ll arrive at 1am SGT / 4am AEDT / 6am in these nations.
Look out – it’s Supergirl trailer launch day!
Happy Supergirl trailer release day, everyone!
I’m Tom Power, TechRadar’s senior entertainment reporter and master of ceremonies for today’s unveiling of the highly-anticipated DC Universe (DCU) movie’s first teaser.
We’re still five hours away from our first proper look at the superhero film, so I’ve got plenty of airtime to fill before it premieres. Luckily for you and me, there’s lots – and I mean lots – to talk about in the meantime. So, strap in, because things are about to get busy.
