There are various rankings of epic movies, with some outlets listing the greatest epic movies of the last 100 years and others focusing on specific time periods, such as the 21st century or the last 75 years. The rankings appear to vary, with different numbers of movies included, such as 10 or 13, and some outlets focusing on specific genres, like historical epics. It is unclear which movies are consistently ranked as the greatest epics, as the lists and criteria seem to differ across outlets.
