When Marvel first announced its plans for Phase 3 of the Marvel Cinematic Universe, Avengers 3 and 4 were both billed as Infinity War - Part 1 and Part 2. However, as the studios' plans evolved, Avengers 4 went back to being an untitled film. And, for a long, long time, Marvel refused to reveal the movie's title. This created immense amounts of anticipation for the title reveal, as fans threw their own theories into the ring.
Finally, the title was revealed as Avengers: Endgame when the movie's first teaser trailer was released last December. When Endgame was revealed as the official subtitle, fans wondered why it had been kept a secret for so long, given that it was one of the theorized titles for the film.
In an interview with Collider, Marvel Studios president Kevin Feige finally explained why there was such secrecy surrounding the title.
"Well, I think I’d said that it all had gotten blown out of proportion to some extent," Feige said. "But it was a spoiler, because if you knew before Infinity War came out that the next movie was called Endgame, then you know that there wasn’t an ending to Infinity War. But that had been the title of the movie from the moment we conceived of doing the two films. In large part, because…it’s seeded right there. I mean, it’s seeded in Ultron."
Here, Feige is referencing a particular scene in 2015's Avengers: Age of Ultron. As fans might recall, after the Avengers' first battle with Ultron, Tony Stark explains that they need to be prepared for whatever alien forces are out there in the cosmos. "That up there, that's the end game," the Armored Avenger says, pointing to the skies.
Therefore, Feige's words makes it clear that the Endgame title had been planned for a very long time. Not only was it mentioned by Doctor Strange in Avengers: Infinity War, it was first seeded in Age of Ultron.
