Last week, the Russo Brothers finally gave the people what they wanted: a name and a trailer for the next Avengers film. But it seems as if some of the film's biggest stars—including Scarlett Johansson—were as much in the dark as the rest of us about the film's title until the trailer dropped.

The epic trailer for Avengers: Endgame went live on Friday, December 7 and became the most viewed trailer in history with 289 million views in 24 hours.

At an event she was hosting for Black Panther, Johansson was asked about the new trailer. According to Fandango managing editor Erik Davis, not only did Johansson not know about the trailer, but she also wasn’t privy to the title of the new movie (despite being in it).

Fellow Avengers actor Sebastian Stan also recently admitted that he had no clue about the movie’s title.

“I didn’t have anything to do with [the title],” Stan said at the 2018 Comic Con Experience festival. “We didn’t know, but also the last thing I filmed was in 2017, which was earlier 2017, so that was a long time ago.”

While there hasn’t been much new information since the trailer and title drop, the Russo Brothers did give fans some insight when they alluded to the fourth film's title while on a press tour for Infinity War. Joe Russo explained that the Avengers 4 title would break new ground in the Marvel Cinematic Universe.

"I don't think there are any comics that correlate to it," Joe told ComicBook.com. "I think we're in pretty fresh territory with Avengers 4. If anything, I think it's interesting after to go back and look at some of the Marvel films and view them through a different lens. But I can't think of any comics in particular that would have value."

Avengers: Endgame is set to hit theaters on April 26, 2019, which is a few weeks earlier than it was originally scheduled to arrive.
