The ongoing attempts to suss out what the name of the fourth Avengers film will be has created its own Twitter microclimate, in which rumors take on lives of their own and steadfastly refuse to die, returning in weird new mutations all the time. One of the biggest of late is the idea that the film has switched titles three times already, and could do again.

Jeremy Conrad, who's an authority on all things Marvel and runs the YouTube channel MCUCosmic , has suggested that the title has changed three times in the last year or so, after various actors and staff accidentally let slip the film's title–or at least its working titles.

Zoe Saldana, who plays Gamora, mentioned the name Avengers: Gauntlet– though that could also be Avengers: Infinity Gauntlet , which sounds a bit over-literal to us and was denied by co-director Joe Russo–while one of the film's special effects workers is said to have let the cat out of the bag while doing a little update on the credits section of his website, where he listed the film's title as Avengers: End Game .

The third potential name is Avengers: Annihilation , which sounds pretty plausible: the comic series explored the cosmic side of the Infinity Gauntlet's universe-halving powers. Some particularly intense fans have said that the Russo brothers' cryptic Instagram post–which asked viewers to "look hard"–backs this up, as the easel and the stepladder in the center of the frame form two As.

Then again, it would be quite funny if, after all this, it was just called Avengers 4 . Not laugh out loud funny, but mildly funny.
