The Spider-Man: Brand New Day trailer release date has been confirmed — and Marvel fans are already piecing it together ahead of time

• The release date for Spider-Man: Brand New Day's first trailer has been revealed
• Lead actor Tom Holland has confirmed it'll drop on March 18
• Marvel superfans have already revealed its first round of footage

It's official: the first trailer for Spider-Man: Brand New Day will be released on Wednesday, March 18 — but you can already watch its first footage right now.

Last Thursday (March 12), a fresh Spider-Man: Brand New Day trailer rumor sparked a new wave of fan excitement that its long-awaited first teaser would arrive on March 18. Five days on from that piece of speculation circulating online, Spider-Man star Tom Holland took to his personal Instagram account to confirm its inaugural trailer will drop on that date.

As part of the below post, Holland also said he'll see us tomorrow morning in New York City. That implies it should be released at 9am ET, which equates to 6am PT and 1pm GMT.

But, wait, there's more, because Holland has also revealed that fans can start piecing it together before the teaser's full unveiling on March 18.

Indeed, starting right now — well, as of 5am PT / 8am ET / 12pm GMT on March 17 — the first clips from Spider-Man 4's first teaser have started to trickle online.

Explaining more in his latest Instagram video, Holland said: "We've had so much love and support from day dot on making these movies and, without that community, there would be no Spider-Man.

"To show you our appreciation, we are doing something that has never been done before. Follow along as a brand new day starts across the world, and some of our greatest fans are going to help us release pieces of our new trailer."

Okay, so how will this work? And how do we find the pieces of said teaser? In the caption accompanying Holland's post, an Instagram handle — pol_deportes — can be seen. Click on the handle, and the first post that appears on pol_deportes' feed contains the very first clip from the new Marvel and Sony movie's trailer. Check it out below (NB: you'll need to flick through to the second video of the post to see the clip):

From there, you can follow this viral Easter egg hunt by clicking the links to other Spider-Man superfans' Instagram accounts in each subsequent post.

At the time of publication, the only other footage I've found is on osuspidey's page. However, with osupsidey passing the baton onto fellow social media user theamazingalexallerano, that's where the next clip will appear. Keep your eyes peeled over there, then, for more footage from the Marvel Cinematic Universe (MCU) film shortly.

It's unclear how many of these clips we'll get, nor do we know if the whole trailer will be unveiled in bite-sized chunks before its grand reveal tomorrow. Considering how long we've had to wait for the Marvel Phase 6 film's first footage, though, you won't find me complaining!
