An event movie or event film is a blockbuster film whose release itself is considered a major event.
It could be a highly anticipated sequel or a big budget film with state-of-the-art special effects or major stars generating considerable attention.

Although it is subjective, what is and what is not considered an event movie, they are usually among the highest-grossing movies in their years of release and become a part of popular culture.
Steven Spielberg’s Jaws from 1975 is the first film that was considered an event movie at the time of its release, but some sources also retroactively apply the term to earlier films such as The Birth of a Nation (1915), Gone with the Wind (1939), and Ben-Hur (1959).
In the 2010’s, other event movies include The Hunger Games (2012), Frozen (2013), Deadpool (2016), and many films from the Marvel Cinematic Universe in particular Avengers: Infinity War (2018) and Avengers: Endgame (2019).
