The final chapter in the Avengers saga grossed $156 million on Friday alone. (Including Thursday night previews.) The previous single-day record was $119 million.
Its market share was approximately 93%. To word that another way, it took in about thirteen times as much as all other films added together. Its predecessor, Infinity War, “only” took in about five times as much as the other films released that weekend.
Coming into this weekend, the weekend record for the entire film market was a gross of $313 million, set during the weekend when Infinity War set the single film weekend record with $257 million. Endgame will gross more than that total market record by itself, perhaps by a very wide margin. (The total for the entire market this weekend will not be that much more than Endgame’s individual total because of that film’s insane level of market dominance.)
Believe it or not, the film’s international box office is even more impressive. Endgame had already shattered the overseas weekend record by Friday and may come close to doubling it by the time the dust clears! By the close of business Friday it had grossed $487 million outside the USA. The previous record for the entire weekend was $443M.
