A new rumor regarding Spider-Man: Brand New Day's first trailer is circulating online
Speculation is rife that the teaser will be released in mid-March
The Marvel Cinematic Universe movie is due out on July 31

Prepare yourselves, fellow webheads, because we might finally, finally get to see the first trailer for Spider-Man: Brand New Day very soon.

After months of speculation, it appears that the Sony and Marvel movie's inaugural teaser will drop in the coming days. Indeed, the rumor mill has gone into overdrive once more, with numerous insiders proposing a new trailer launch date of Wednesday, March 18.

Now, before we continue, I want to stress that this is just a rumor. There have been plenty of those concerning the arrival of Spider-Man 4's trailer, so this is by no means confirmation that it'll premiere on the aforementioned date.

Industry insiders Grace Randolph and Alex Perez — whose track records admittedly aren't the best — have floated the possibility that the film's first footage will be publicly unveiled in the near future. And, with a more reputable leaker in the form of Crypic4KQual implying that there's some substance to the March 18 rumor (see below), I'm praying that these claims are accurate.

If — and, again, it's still a big if at this stage — the Marvel Phase 6 movie's first trailer debuts next week, it'll mark the end of what's been a testing time for Spider-Man fans who've been desperate to see some footage.

Last December, an extremely low-quality version of the first Spider-Man: Brand New Day trailer leaked online. In the aftermath of said leak, some theorized that Sony would immediately release a high-definition version to patch up the leak.

Long story short: it didn't. However, when another Spider-Man 4 trailer rumor emerged online in January, fans were given fresh hope that Sony was gearing up to release the Marvel Cinematic Universe (MCU) flick's first teaser. Again, though, the date it was claimed to be releasing on — January 19 — passed without incident.
