After a weekend that saw the Marvel Cinematic Universe once again assert its dominance over the pop culture landscape, Marvel Studios will now see its lifetime box office grosses cross the $20 billion mark after “Avengers: Endgame” entered the top 10 all-time box office list on Monday.

The superhero crossover’s first weekday in theaters was also the opening day for the final market to receive the film — Russia. There, the film made $7.8 million and set a new record for the highest opening day in that country, 59% ahead of the previous record set by “Avengers: Infinity War,” which opened on a Thursday.

On the domestic side, “Endgame” grossed $36.7 million, the second highest total ever recorded on a Monday behind the $40 million made by “Star Wars: The Force Awakens” in 2015. That total is also down 60 percent from the $90.3 million opening “Endgame” made on Sunday. By comparison, “Infinity War” made $24.7 million for a 64% day-to-day drop.

This is an early sign that the second weekend of “Endgame” is going to be one of the largest in industry history, and will likely mean that the film will hit the $2 billion mark in the same time that it took “Infinity War” to hit $1 billion. Already after six days in theaters, “Endgame” has reached a global total of $1.34 billion, leapfrogging films like “Frozen,” “Jurassic World: Fallen Kingdom,” and “Star Wars: The Last Jedi” to enter the top 10 highest grossing films of all time.

For Marvel Studios, this is a capstone moment in its rise to box office dominance since it first released “Iron Man” 11 years ago. As of today, Marvel Studios has produced half of the top 10 highest grossing films of all time before inflation adjustment, those five films being “Black Panther” and all four “Avengers” films.
