"Biographical movies have always been pretty popular, especially around awards season, for better or worse. If someone lived an interesting life and achieved some sort of level of fame during said life, then there's a good chance they'll get a movie made about them eventually. Lots of the time, these movies focus on musicians, like 'A Complete Unknown' (Bob Dylan) or 'Bohemian Rhapsody' (Freddie Mercury), but the biopic genre spans out well beyond the world of music. Sometimes, filmmakers do indeed choose to make movies about filmmakers. Certain prolific or culturally significant directors have stories worth telling, with these stories often being about how those filmmakers told stories. Also, a few filmmakers have made biographical films about themselves, or inspired by their real lives in some way, and a few of those have also been included in the ranking below." - collider.com
