You know when you finish watching some movie trailers and you think, "Wow. That just gave away the plot of the entire movie!"
The new Avengers: Endgame trailer is the complete opposite of that.
Marvel Studios dropped the official clip online late last night to mark the six-week countdown until the fourth Avengers movie hits cinemas.
Unsurprisingly, it's thrown the internet into a tailspin, despite a pretty significant portion of the trailer consisting of old footage.
It's all very dark and mysterious and brooding and, aside from confirming that the gang's getting back together to take on Thanos, there's really only one major spoiler.
In the interests of some of you maybe not wanting it to be pointed out, we'll wait until after the trailer to tell you.
The eagle-eyed among you may have spotted that the group shot of the Avengers in their Quantum suits answers a question from the end of the last Avengers movie: Does Tony Stark make it back to earth?
Well, if that slow-mo shot of him striding in formation is anything to go by, yes - and so too does Nebula.
Fans have, understandably, lost it, although some are theorising that this could be the Tony from the past; unfortunately, it doesn't look like any of those questions will be answered before April 26.
What IS a definite, though, is that Captain Marvel will join the battle against Thanos, a development Thor seems pretty pleased about.
Avengers: Endgame hits Australian cinemas April 26.
