Supergirl trailer launch live: all of the build-up, news, and rumors before the DCU movie's teaser is released
The first Supergirl trailer will be released later today (Thursday, December 11)
Is it a bird? Is it a plane? No, it's the launch day for Supergirl's inaugural teaser trailer!
With DC Studios officially confirming that Supergirl's first trailer will be released on Thursday, December 11 at 9am PT / 12pm ET / 5pm GMT, the countdown is on to its arrival. And, if it wasn't obvious, we'll be covering the build-up to its world premiere, the teaser's reveal, and then breaking it down everything it shows us post-launch.
If you're as excited as we are for the next DC Universe (DCU) movie's first official footage to drop, you'll want to stick us throughout the day – and, potentially, tomorrow, too – for the biggest news, latest rumors, and other coverage on it.
So, grab some food, sit back, and let's wait for the teaser's unveiling together.
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."

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.
