Marvel just keeps playing with us.

Fans are still hoping the possibly depressing title for 2019's Avengers 4 will be released, though it's looking less and less likely.

Then, on Wednesday, Marvel rolled out a sneak peek at Avengers 4 at the CineEurope conference in Barcelona, according to The Hollywood Reporter.

But don't expect to see it online any time soon.

Conference attendees weren't allowed to have phones in the room, reports.

It's possible (who are we kidding, it's LIKELY) fans will eventually spill the beans on social media, but the footage itself will likely stay hidden, just like the Infinity War footage that was shown at last summer's ComicCon and D23.
