This week has seen Marvel Studios plagued by leaks. The first Avengers: Doomsday teaser trailer showed up on social media on Monday, despite the plan being for it to premiere exclusively in theatres in front of Avatar: Fire and Ash this weekend.
Audio from the second sneak peek—revolving around Thor—has also done the rounds, as have vague descriptions of the third and fourth teasers (those supposedly place Loki and Doctor Doom front and centre).
Then, there was the Spider-Man: Brand New Day trailer. That reportedly originated from an invite-only website where people can rate upcoming previews to provide movie studios with feedback. The quality was poor, but it's the real deal and still out there if you look hard enough.
Now, we have what appears to be the composer Alan Silvestri's X-Men theme from Avengers: Doomsday. This comes from a now-restricted X account that's been sharing a lot of seemingly accurate details about the movie's marketing campaign this week.
Having looked a little further into this, it seems many of these leaks are coming from VFX companies working on Avengers: Doomsday. It's also possible that this theme is part of an upcoming sneak peek, especially with rumours swirling about a fifth teaser that should be more of a traditional trailer.
Avengers: Doomsday's X-Men team is currently comprised of Professor X, Magneto, Cyclops, Beast, Nightcrawler, Gambit, and Mystique. However, we expect Wolverine, Storm, Binary, and Jean Grey to also appear.
