As of October 2023, the most watched movie of all time in terms of box office gross is "Avatar" (2009), directed by James Cameron. It has reclaimed its top position following a re-release in 2021, surpassing "Avengers: Endgame" (2019). However, if considering viewership across all platforms, including television and home media, this metric can vary, and no definitive title can be claimed. Box office figures are the most common measure for popularity in cinema.

The very first horror movie is often considered to be "Le Manoir du Diable" (The Haunted Castle), a short silent film directed by Georges Méliès in 1896. The film features a devilish figure conjuring various supernatural elements, including bats and ghosts, in a whimsical tale set in a castle. While it is brief and comedic in nature, it laid the groundwork for the horror genre in cinema. Other early horror films include "The Cabinet of Dr. Caligari" (1920) and "Nosferatu" (1922), which further defined the genre's themes and aesthetics.
