This is a project I started in 2016. After recently clearing out some files on my laptop, I recovered my original data and decided to enter data for the past four years.
This graph illustrates the results. Using
Box Office Mojo's weekly listings, I assembled lists of the highest-grossing movies in America for each week out of the year, and for each year since 2000. I then categorized each highest-grossing film as either an "original" film or "not original." Some classifications may be debatable, but this was my methodology:
1) If a movie uses a preestablished consumer property to propel its success, then it is considered "not original" even if the script is entirely new (e.g.
The Lego Movie).
2) If a movie is based on a novel, even loosely, it is considered "not original" (e.g.
Gone Girl).
3) If a movie is a prequel, sequel, remake, reboot, or spin-off of another existing property, it is clearly "not original" (e.g.
Batman v. Superman).
4) If a movie is based on a piece of folklore, or assembled from folklore from other cultures that has never before been made into a movie, then it may be considered "original." Movies like these typically do not use the preexisting story to propel their success, and the original story provides only a general blueprint for the screenwriters (e.g.
Frozen).
5) Finally, if a movie is based on historical events, but is not based on any particular authoritative historical text, then it may be considered "original." These movies often create new characters and take a degree of creative license in their storytelling, rendering them more "original" than a movie that adapts a particular novel or factual book about a historical event (e.g.
Dunkirk).
In any event, point #4 typically only applies to Disney movies, while #5 is extremely rare. Altering these classifications would not significantly change the data here.
-------------------------
Now, on to analysis. Here are a few things that stand out:
1) Since 2000, the number of high-grossing original films in the US has dropped precipitously. They have been replaced mostly by Marvel movies and remakes/reboots of older films (e.g.
Jumanji).
2) Through a twist of fate, 2020 became the "best" year for original films this century-- though obviously that is not exactly a blessing. Many big-budget franchise films were delayed and pushed back from 2020, which may explain why they recovered so quickly in 2021.
3) 2018 is the worst year on record for original films. Out of 52 weeks in the year, only four weeks (~8%) were not dominated by franchise films.
Feel free to examine the data for yourself; it's quite depressing. The only original films to reach the coveted spot of "Number One Movie in America" that year were
A Quiet Place, a critically panned Kevin Hart comedy called
Night School, and
The Meg-- which I'm now realizing was loosely based on a book, which makes its inclusion in this list highly debatable.
