Highest box office film gross - single day's takings

The movie with the highest box-office gross in one day is Avengers: Endgame (USA, 2019), which took an unprecedented $157,461,641 (£122.0 million) on its first full day of release in the USA alone on 26 April 2019.

This one-day gross, from 4,662 cinemas, puts Endgame ahead of Star Wars Ep. VII: The Force Awakens (2015), which earned $119,119,282 on its opening day of 18 December 2015. The movie - the sequel to 2018's Avengers: Infinity War - also secured the record for the highest-grossing movie on a non-opening-day when it earned $109,264,122 on day two of its domestic release.

Endgame went on to gross nearly $2.8 billion at the worldwide box office, making it, as of January 2021, the most successful movie of all time.
