List of longest films by running time

This is a list of films whose running time exceeds 300 minutes (five hours).

While most cinematic films have a broad theatrical release in multiple locations through normal distribution channels, some of the longest films are experimental in nature or created for art gallery installations, having never been simultaneously released to multiple screens or intended for mainstream audiences. They may have been shown in venues where audiences were only expected to view a portion of the film during its screening.

Note: Some releases are extended cuts or director's cuts, and are ranked according to the longest verified running time.

The original version of Erich von Stroheim's Greed reportedly ran at about 10 hours. However, it was only ever shown once at this length, and no such copy currently exists. The length of the final release (edited against von Stroheim's wishes) was approximately 2 hours 20 minutes. Subsequently rediscovered footage has let researchers reconstruct something closer to four hours. Similarly, Sion Sono's Love Exposure ran approximately 6 hours before being edited down to four at the behest of the producers. A 2-hour version was attempted but ultimately deemed "impossible", according to Sono. Sono currently has no plans to publicly release the 6-hour cut.

This section lists films conceived as an artistic unity and produced simultaneously, or consecutively with no significant interruption or change of production team, even though they were released with separate premières.
