Supergirl trailer launch live: all of the build-up, news, and rumors before the DCU movie's teaser is released

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.

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.

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.
