Avengers: Infinity War wasn't just one of the biggest films of 2018 -- it was one of the biggest films of all time. The third Avengers film set the record for the biggest film opening in the United States, even surpassing Star Wars: The Force Awakens, with a staggering opening weekend haul of $257.9 million.

But now, with Avengers: Endgame set to arrive at the end of the month, industry projections suggest that the newest Marvel Cinematic Universe film may very well surpass  that impressive number. But just how much money is Endgame expected to make in its opening weekend?

According to The Hollywood Reporter, indicators for the film's success have already led some to predict Avengers: Endgame could easily surpass the previous Marvel film become the biggest domestic weekend in cinematic history. Early projections say that the film will earn somewhere between $200 and $225 million domestically in the opening weekend of release.

While this is far less than the ultimate take of the previous film, it's important to remember that Infinity War wasn't projected to do that well, either. In fact, industry projections in 2018 imagined that Infinity War would earn between $185 and $225 million in its first weekend of release. That the film managed to earn considerably more than that proved the MCU films, especially the big events, have more pull on audiences than analysts realized. It also means that the same might be true for Endgame.

The overarching story of the Infinity Stones that has formed much of the backbone of the MCU so far will presumably come to a close with Endgame. There's also the question of what will happen to the various heroes who were reduced to ash by Thanos in the climax of the previous film, with the fates of fan favorites like Black Panther, Spider-Man (OK, we know Peter Parker's coming back) and the Guardians of the Galaxy to be revealed in the sequel. Those two factors mean it's more than possible that box office analysts are underselling the Avengers films once again.

If Endgame performs along the same line as Infinity War, it may approach $300 million domestic box office in its opening weekend. To do that, Endgame would have to earn an additional $40 million on top of the $257 million needs to unseat Infinity War as the biggest domestic opening in cinematic history. A tough goal, especially for a movie that clocks in at just over three hours in length, but if any movie has captured the zeitgeist of the current culture well enough to pull it off, it might just be Endgame.

Directed by Anthony and Joe Russo, Avengers: Endgame stars Robert Downey Jr., Chris Evans, Mark Ruffalo, Chris Hemsworth, Scarlett Johansson, Jeremy Renner, Don Cheadle, Paul Rudd, Brie Larson, Karen Gillan, Danai Gurira, Benedict Wong, Jon Favreau and Bradley Cooper, with Gwyneth Paltrow and Josh Brolin. The film arrives April 26.
