Avengers: Doomsday's third teaser trailer—which will revolve around the X-Men—has been sent out to theaters. However, while it's currently locked (meaning it needs a code to be accessed), we'd expect it to leak online by Monday or Tuesday at the latest.
The brief teaser will have a runtime of 1 minute and 10 seconds, suggesting we'll only get a glimpse of what to expect from the returns of Professor X, Magneto, and Cyclops.
Thanks to another international ratings board, we can today confirm that Avengers: Doomsday's fourth sneak peek will run for a total of 1 minute and 20 seconds. As a reminder, the Fantastic Four and Wakanda are expected to be the focus, though what we'll see from a teaser that supposedly revolves around The Thing and Shuri is very much a mystery to us as of now.
Franklin Richards is expected to play a significant role in Avengers: Doomsday, as is Toussaint/T'Challa II, if reports that he's being aged up to become the MCU's new Black Panther are correct.
What has become clear is that we're not getting a teaser focused on Robert Downey Jr.'s Doctor Doom. Instead, it seems Marvel Studios will make us wait to learn more about what to expect from the Oscar-winner's take on Victor Von Doom.
Over the summer, Ebon Moss-Bachrach was asked to describe Avengers: Doomsday and called it, "Epic. Tragic. Intergalactic. Starry." His co-star, Human Torch actor Joseph Quinn, did the same when he said, "Epic, mental, Downey Jr."
