Back in 2014, Marvel Studios president Kevin Feige gathered fans together for an impromptu event where he announced the entire lineup of Marvel’s Phase 3 films. At the very end of Feige’s timeline was Avengers: Infinity War Parts 1 and 2. Subsequently, Marvel decided to change the name of the second movie and withhold the actual title for Avengers 4. But if Feige had it to do over again, he probably wouldn’t opt for the secrecy.
"I've said before, it's gotten entirely out of hand,” Feige told IGN during the Infinity War press junket. “And now will have no chance to living up to any expectations of what it's gonna be. And it sort of backfired, if I'm honest with you, because the notion was to not talk about it so the focus was to be on [Infinity War]."
Feige expanded on his reasoning for this decision and admitted that it may have also been a mistake to reveal Infinity War as the MCU’s end goal four years before it came out, because it may have taken away the focus from Avengers: Age of Ultron. While Avengers 4 is no longer called Infinity War Part 2, Feige once again confirmed it is directly connected to its predecessor.
"They’re absolutely directly connected, as many of our movies are but more so than many of our other movies," said Feige. "People will want to know what happens next immediately at the end of it."
Currently, Avengers 4 is slated to hit theaters on May 3, 2019. But if Marvel and Disney decide that the beginning of the summer movie season now starts in the last weekend of April, then that could potentially change.
