As Infinity War’s post-credits sequence hinted, Captain Marvel is going to be integral to the plot of Avengers 4. Turns out that Captain Marvel is also going to be very important when it comes to the film’s still unconfirmed official title. Marvel Studios president Kevin Feige says that the subtitle won’t be revealed until after the first teaser for Captain Marvel comes out, which will be towards the end of the year.says that the subtitle won’t be revealed until after the first teaser for Captain Marvel comes out, which will be towards the end of the year.

Feige sat down with Collider at a press day for Ant-Man and the Wasp and revealed that the much-speculated upon subtitle will continue to be speculated for a while.

“That’ll be after the Captain Marvel teaser probably, announcing that title,” he said. “It’ll be towards the end of the year with however we launch that film.”

The Avengers 4 title is still a secret because, as Feige explained shortly before Infinity War came out in April, it’s a huge spoiler. It’s supposedly so big a secret that even the cast doesn’t know what the movie is called, though this could be a little bit of subterfuge on Marvel’s part. Still, Marvel is going to need to reveal what the title is and “spoil” the movie at some point, and it’s looking like late 2018 is when that will be.

For what it’s worth, Marvel announced the title of Infinity War — then known as Part 1 — way back in October of 2014, more than three years before Infinity War’s April 2018 release. It’s interesting then, that in the name of preserving a secret that will have to be spoiled eventually, Avengers 4 still doesn’t have a name an it’s less than a year before its May 3 premiere.

Captain Marvel comes out on March 8, 2019, and the first trailer will, it would seem, come out later this year.
