Ask Slashdot: Are Movies Becoming More Derivative?

Film data researcher Stepehen, writing on his blog: This may surprise some, but since 2000, just over half of all movies released have been original screenplays. The most common source for adapted screenplays was real-life events, accounting for almost a fifth of movies made between 2000 and 2023. (Typically, in these cases, the filmmakers will have paid for the rights to a nonfiction book or two that covered those events, but we will classify that as 'based on real-life events' in this analysis.) Other sources include fictional books/articles (8.9%), previous movies (11.8%), stage productions (including plays, musicals, and dance performances) (1.5%), and TV/Web shows (0.9%). In the chart below, 'Other' includes myths, legends, poems, songs, games, toys, and more.

How has this changed over the years? Forty years ago, about the same proportion of movies being made were original screenplays as they are today. That's quite surprising -- both because I assume that many people expected it to be lower in recent years, but also because little stays the same in the film industry over such a long period of time. But when we look at a time series by year, we can see that it hadn't plateaued. During the late 1990s and 2000s, original screenplays declined markedly and only rose again in the 2010s.
